Puking Pumpkin Science
Add a dash of spooky science to your Halloween decor — with an eerie, oozy chemical concoction you whip up yourself! Put your measuring and color-mixing skills to the test while blending together baking soda, foaming gel, and liquid colors. Pour the mixture into a carved pumpkin from home, add water and citric acid, then sit back as the chemicals react and make your pumpkin “puke”! Barf has never before been such a blast.

Behind the design
“What do you do when pumpkins are out of season? You get creative! We had to figure out exactly what ingredient amounts we needed to make a massive, messy chemical reaction. But since we couldn't use a real pumpkin for our tests, we used a jack-o'-lantern bucket instead!”
- KiwiCo Product Designer

This was a hit! It came just in time for our Guy Fawkes night so he got to do the experiment with his aunty. The expression on his face was priceless! Thank you!

Bought as a gift for a very hands-on 5 year old who absolutely loved it. Parents reported that she loved it so much we she won't stop asking for pumpkins to keep doing it to!

My grandson absolutely LOVED this kit! I had to buy another kit because he was so excited. Great kit, the directions were helpful and on point. One of the best kits offered.
