More fizzy fun and games: build a submarine that will sink and come back to the surface.
- small soda bottle
- marbles
- baking soda
- vinegar
- Using a small soda bottle, marbles, and baking soda and vinegar, build a submarine that will sink and come back to the surface. The one that does this the fastest wins.
- By the way, you can't touch the submarine once you put it in the water, but you can leave part of the submarine at the bottom of the water.

When I did the submarine race my submarine would not sink. I put rocks, vinegar, and baking soda in the bottle. I then sealed the bottle. What did I do worng?

Instead of squezing the air out of my bottle I attached a balloon on top of the bottle and I used fishing waits and marbles to sink it.
