“Foaming Halloween Pumpkin” experiment

How to make a pumpkin overflow with foam

Hal­loween is com­ing soon, it’s time to get ready! Have an orig­i­nal foam par­ty!

Reagents and equip­ment:

  • pump­kin;
  • 30% hy­dro­gen per­ox­ide;
  • food col­or­ing;
  • liq­uid soap;
  • yeast;
  • three cups.

Step-by-step in­struc­tions

Pre­pare a so­lu­tion for the foam: pour green food col­or­ing, liq­uid soap and hy­dro­gen per­ox­ide into the first cup. Mix the so­lu­tion with a spoon. Mix yeast and wa­ter in the sec­ond cup. Put a third cup into the Hal­loween pump­kin and add the mix­ture from the first cup. Then add the mix­ture from the sec­ond cup and put the lid on the pump­kin. Green foam will start to pour out of the pump­kin’s mouth and eyes.

Pro­cess­es de­scrip­tion

Yeast acts as a cat­a­lyst in the break­down of hy­dro­gen per­ox­ide into wa­ter and oxy­gen. The oxy­gen makes the dish­wash­ing liq­uid foam abun­dant­ly. Thick green foam gush­es out of the pump­kin’s eyes and mouth. The pump­kin just over­flows with joy!

Safe­ty pre­cau­tions

30% hy­dro­gen per­ox­ide leaves burns on the skin – ob­serve safe­ty rules.
