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!

Both boys were fascinated by this. The 7 year old loves all the projects he's received.

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!
