Can you blow a balloon up without using your mouth?

Equipment:

1 balloon

baking soda

vinegar

funnel

spoon

We are learning to make predictions.

* Some thought the balloon 

would stay floppy.

 * Some people thought it would get bigger like when you blow into it. 

 * Some people thought it would explode all over the room.

 The baking soda mixed with the vinegar and caused a chemical reaction.

They created a gas!

 Yes you can blow a balloon up without using your mouth :)
