we are doing the 50 Dangerous things (you should let your children do) #9

We had all the ingredients we needed in the cupboard- cider vinegar, baking soda, water and paper towels.

We used a large baking tray to keep any mess we made contained. We all took turns at guessing what would happen. I guessed the bag would break and cause a leak before anything happened. Everyone else was very optimistic and guessed we would get an explosion and it would make a mess everywhere.

We watched and waited after putting everything in the ziplock bag....

 and waited....

and waited....

and waited as the bag slowly expanded...

and nothing really happened so we all agreed it was time to start a new bag with the same ingredients and use a tissue instead of a paper towel.

This time it was much quicker as the bag expanded....

and we got a POP as it expanded to full capacity and the the seal of the zip lock bag at the top burst open! We got the pop we were waiting for!
