Rocket Boat Chemical Reaction Science Experiment
In this fun and easy science experiment for kids, we’re going to use a chemical reaction to make a rocket boat.
- Plastic liquid dish soap bottle with a pop top spout
- Food coloring
- Toilet paper
- Baking soda
- Toilet paper
- Fill a bathtub with about six inches of water.
- Open the pop top on the plastic bottle.
- Unscrew the cap and add one and a half cups of vinegar to the bottle.
- Add a few drops of food coloring.
- Put one tablespoon of baking soda into a square of toilet paper.
- Fold up the toilet paper to create a little pouch and secure it with a small piece of tape. Make sure the pouch will fit into the mouth of the bottle.
- Drop the baking soda pouch into the bottle and quickly screw on the cap.
- Release the bottle into the water and watch your rocket boat propel itself around the bathtub.

How it Works:
The baking soda and vinegar, when combined, create a chemical reaction. This chemical reaction produces carbon dioxide gas. The gas quickly builds pressure in the bottle. When the air escapes through the pop top, it propels the rocket boat through the water.
Make This A Science Project:
Try different acids like lemon juice. Try different amounts of baking soda. Try different amounts of vinegar. Try adding salt to the experiment.
