The Mad Science Party Lab – 8 Tips for Explosive Fun!
I’m excited to share some creative tips and ideas from my daughter’s Mad Science Birthday party with you… finally! She’s 8-1/2 now, and this is her 7th birthday party. 😳😂
Anyways, aside from the abundance of “experiment messes” around the house, I really love that Macy has been crazy about science for a few years now. This was a super fun party theme to work on with TONS of room for creativity – especially in the treats department. (Hello, Petri Dish Jello and Radioactive Punch!) 🥳

THE ELEMENTS OF FUN
1. Hands-on Experiments
Set up stations with simple experiments that kids can try themselves, like baking soda & vinegar balloons.
We saved small Gatorade bottles for this activity and pre-filled them with vinegar. The balloons were also pre-filled with baking soda, so kids could just grab a balloon and put it on a bottle, then watch the balloon *magically* inflate. Using balloons with design on them – like these polka dot and marbled balloons – makes this activity even more fun to look at!
Candy molecule building is another super easy activity that doesn’t make a huge mess. 🙌 Set out trays of “squishy” candy (like spice dots, marshmallows, etc) + toothpicks and let kids build their own candy molecules! It’s a good idea to set out a some pre-built models for them to copy, and there are lots of great examples available if you do a goole image search for “candy molecules”.
2. The Mad Scientist
From crazy hair to a giant mustache, bring in signature “mad scientist” details for a touch of zany flair. I loved the idea of greeting guests at the door with a giant, playful nod to our mad scientist! We also had colorful “safety glasses” for all of the guests to wear.
3. Laboratory Treats
This is where things can REALLY get creative! We served up science-inspired treats like “Petri Dish Jello”, gummy frog “Specimens”
white chocolate “Lab Rats” (made using this candy mouse mold), and rock candy stick “Geodes”.
I especially love how the petri dish jello dessert turned out:
This scientific and gross-in-a-good-way treat is easy to make! Just pour liquid jello into Petri dishes (about halfway full). If you’re using gummy worms or other big gummies, you can then add them in now.
Refrigerate for about an hour, then add some sprinkles and continue to refrigerate until serving. The sprinkles will kind of bloat and “bleed” out into the jello after a while, resembling “bacteria” that’s growing! I also added a strip of washi tape to “package” the treat.
4. Printable Fun
Printables are my favorite quick & easy way to play up any theme! I designed a bright and colorful science inspired collection for this party featuring playful (and yes, maybe a little bit nerdy 🤓) science puns like “Of QUARTZ, Geology ROCKS” and “DISCOVER something fun”!
5. Bright Ideas
Fill plastic light bulb containers with colorful candy for party favors with creative *spark*!
I used a mix of regular and pastel M&Ms to fill these light bulbs… and yes we DID pick out all the pieces that didn’t match the party’s palette. Looking at you brown and orange! 😜 It’s less expensive to buy bags of regular M&Ms and remove certain colors than to buy the specialty packs that are all one color.
(P.S. The giant plastic lightbulb decoration above was also an Amazon purchase!)
6. Giant Atoms and Molecules (DIY Decor)
This was probably my favorite decoration – possibly because I just love anything that you can hang overhead! These giant “atom & molecule” decorations are made from embroidery hoops (spray painted silver), colorful “ball pit” balls, and wooden skewers. I used fishing wire to hang them for a “floating” effect.
7. Mad Science Show
Live demos are always a hit with the kids! We hired a pro from Mad Science of Sacramento to put on a cool science show that was centered around gases, chemical reactions, and “things that go pop and fizz”. She also led the kids in a bouncy ball making activity and explained the science behind cotton candy making… while making it. And then of course the kids scarfed it down!
8. “Experimental” Decor
These science-inspired decoration ideas are quick, stylish, and won’t break the bank!
- Colorful Chemistry
This is as easy as it gets! Just fill glass beakers with water and food coloring. We also dropped dry ice into them a few times – especially when guests were first arriving. However, just a heads up that the dry ice doesn’t last very long with the small pieces that you have to use in order for them to fit inside the narrow mouth beakers. - Petri Dish Specimens
For these, I printed scientific-looking patterns out on transparency paper and cut them to fit inside large Petri dishes. A plastic insect or butterfly was placed on top, then covered with the petri dish lid. Done! - Biohazard Caution Tape
This bright yellow tape is a great way to make a big impact on your space without spending much at all. Doors, fences, etc… it makes an easy photo backdrop too! - Test Tube Insects
To make these, just stick plastic bugs and butterflies into clear test tube containers (I used these large plastic ones) and fill them with water. It’s actually best when the fit is a little snug, because the insects get suspended in the tube, making things look all the more “science-y”.
The acrylic stand I’m using here is actually an ice cream cone holder! I bought this one probably 10 years ago, but you can find similar ones here and on Amazon.
I hope some of these ideas help you plan your own *explosively fun* Mad Science Party! 😉🧪🥼🔬🧫

You can rent a cotton candy machine from us if you’re in the Jacksonville FL area! Find us at https://www.bounceitoutparty.com/jacksonville-fl/
Hi there,
I’m hosting a birthday party at home for the first time and I’ve decided to do little science experiments with my son’s 6 year-old friends. I would be so grateful if you could share your fabulous printables with me.

What an amazing article. I really loved the insects in test tubes. I was a total science nerd at high school so I really need to do this for my son’s 9th birthday. It is not really for this age group but I also came across a science party game for adults. It was called Chemical Catastrophe and I found it at Chemical Catastrophe Murder Mystery Party.
Do you think I could get the test tubes on eBay? Thanks so much.
Pucker powder is good to eat and can make a good science project to see what color make different colors.
This also has different flavors too
Hi Lisa! Just sent them to you via email. :)
Hi Jenn
You did a phenomenal job. Love your printables.
Hi Jenn
These are awesome ideas …I am planning for a science theme party for my son

Kaki
Hello! This is such a great theme and you’ve done a wonderful job! Are you please able to share the template for the door decoration if you have it? Also do you have a link or know where I can purchase the little sign holder things? Sorry I don’t know what they’re called! I’m planning a science party for my almost 6 year old thank you, Kimberley
Just emailed you :)
Good evening I am Linda and I am teaching science in 4th grade for the first time…. I would love to create my own atoms and molecules decor
Hi Linda – They’re really easy to make! I just bought cheap wooden embroidery hoops and fit them snugly together, then secured with hot glue. The balls were purchased on Amazon. Here’s the link. For some of the balls I just used a sharp tool to pierce them first, then inserted the wooden skewers. For others I just added a dab of hot glue to the top of them to secure fishing wire. Hope that helps and good luck! :)
Hi!
I love this theme. I am thinking of doing a Mad Scientist party for my End of Year party with my second graders.
Such a cute idea! This is the perfect party theme for my 6 year old daughters upcoming birthday party, such a fresh idea! Thanks so much for sharing! :)
Love this! I’m interested in how that punch was made. Can you share the recipe?
Thanks so much!!
Best,
Summer
Hi Summer! The punch is just Green Hawaiian Punch (1 jug) + a large can of pineapple juice (46 oz) + ginger ale (2L bottle). Then I added a little dry ice right when the party started for the “wow factor”. ;)
Hi there! Love these ideas, thanks for sharing. I was planning on doing a Mad Science Party for my son :).
Awesome inspiration and printables! Would you mind sharing with me for my daughter’s birthday?!

Where did you get the large lightbulb??! It’s fantastic and I’m in love with the whole theme! So many great ideas!
Thank you, Betsy! Regarding the light bulb lamp, I bought it on Amazon, but it looks like the company either doesn’t make it anymore or it’s out of stock. :( Here’s the link just in case. Sorry I can’t be of more help!
Omgosh this party is so cute! Is there a way to get the printables?!
just emailed you :)

I’d love the printables! We are having a mad scientist party for our8 year old in a few weeks.
I love all of this ideas! I’m interest on the mad scientist door printables.
I love your creativity! My soon to be 8 year old will love this. She’s been asking for years.
Thank you!!
just emailed you! :)
This is an awesome idea! I was wondering where you got your Mad Scientist door decoration file from? If you could share that would be fantastic! Thanks.
Hi Julia – The door decoration is a printable I put together myself, so it’s more of a DIY project. I just emailed you the file. You can print it somewhere like Staples or FedEx office (it’s a large format size) and then just cut the pieces out. Takes a little effort but worth it in my opinion… our party guests all loved being greeted that way at least. ;)
I love everything about this!
Hi,
My name is Samantha Velosky! I would love to know how to get the printables?
I am on the board of PTA at my children’s school and we are planning a Mad Scientist Membership Drive.
I love the door, I am a biology teacher and I would love to print this for my door!
Would you share the cut out with me?
I would be so excited because that is awesome!
Hi, I am planning my sons 8th birthday and I would love these printables. They are adorable and exactly what I had in mind.

Throwing my son a scientists birthday party next weekend and I would love to know where I can get those printabls…they would be perfect. What did you make for them to drink? Looks green and sciencey?
Just emailed you. :) And The green punch was just made from Green Berry Rush Hawaiian Punch and Sprite… and then we added some dry ice at the beginning of the party. The dry ice doesn’t last super long, but it sure looks fun while it does! :)
Hello, I love everything about this party!!! Im so interested in the templates.. is there any way you can share those with me? Or how do we buy?? We are excited about our upcoming Science Party!
Brenda
Bravo!!! I’d also love the files to print these awesome designs! I especially love the door scientist!! My daughters birthday part is on the October 26…hopefully you see this in time!
Omg!!!! I’m helping my sister throw her son’s 8th birthday party (her first time hosting)…she’s soo stressed out. Just shared you ideas with her…she absolutely loved everything!!!
Just emailed you! :)
What an awesome party! I was stressing over a “favor” idea and you have inspired me! Thanks !!
I love your science party ideas and wonderful printables! I am also curious where you found the stand for the test tubes with the bugs inside. Thanks so much!
Hi Erin – Thanks for the kind words! The stands I used for the “test tube bugs” are actually acrylic ice cream cone holders. :) You can find a similar ones on Amazon right here – or at places like Displays2Go.
Regarding the printables – they’re now included with Design Hero, which is a new creative platform I launched, so I’m not able to give them away for free anymore. But the new ones are fully editable (the other ones I used to share weren’t), which means you can put your child’s name in the signs, put your own food names in the tent cards, etc. And there’s even an invitation and additional designs included now.:) You can take a closer look at everything here: https://www.hwtm.com/printables/mad-science-birthday-party/
Hope that helps, and good luck with the party!
My wife and I have been scratching our heads trying to choose a theme for our son’s birthday party next month. I like that you mentioned a science-themed birthday party will allow the kids to participate in hands-on experiments like baking powder and vinegar balloons. I will survey for party planners that had previously done a science party and will propose the idea to my wife.
This is awesome and perfect for my little one’s big day! Thank you :)
Hi Shweta – Thank you for the kind words! These printables are now available with a Design Hero Membership – and you can even customize them instantly online! You can find this collection right here: https://www.hwtm.com/printables/mad-science-birthday-party/ Please let me know if you have any questions! :)
What a fun party theme! My daughter loves science and doing experiments. She will flip for this!
