Puking Pumpkin Science


What you get

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.

• Includes enough baking soda, foaming gel, and citric acid to make several pumpkins puke. Just add the pumpkins!

• Also includes scoops, a flask, and a funnel to measure out your materials and pour them into your pumpkins.

• Get creative with customization! Pick from one of 3 included liquid colors (red, blue, and yellow), or experiment with color mixing to create a brand new color of barf!

• Instructions foldout includes an exploration of bubbly chemical reactions, fun facts about pumpkins, and a look inside the crate’s design.




From the desk of the product designer:

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!

By the numbers

Jack o'-lantern bucket tests: 10

Names we considered before landing on Puking Pumpkin: 13

Hours spend searching for pumpkins to carve in the middle of April: too many!

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.
