We filled a bottle about 1/2 full of vinegar. Anna carefully put baking soda into the balloon. Then she had to put the balloon onto the bottle.

Anna held up the balloon so that the baking soda went in. The balloon started to blow up. We were worried that the balloon would explode.
Anna did the experiment again but this time she put more baking soda in.

  1. Wow! Room 4, Room 10 has also done the inflatable balloon trick, but we had a little amount of vinegar so our balloon didn't inflate as much as we wanted it to. It still worked a bit.
