Unplugged Project - Bottle

We participated in this week's Unplugged Project again. The theme this week is Bottle!

Here is a description of the science project lead by my sweet husband.
Take an empty wine bottle and put some vinegar in it.
Then take a balloon and put some baking soda in it.
Carefully without spilling the baking soda, slide the opening in the balloon onto the top of the wine bottle.
When ready, pick up the top of the balloon so that the baking soda spills into the bottle.
When baking soda and vinegar mix, the released gas blows up the balloon.
