KITCHEN SCIENCE LAB | DIY jet boat. Power boat science experiment with baking soda. @kitchensciencelab1312 | Uploaded July 2022 | Updated October 2024, 5 hours ago.
🔻 We need:
- A wide-necked bottle (0.3 or 0.5 liters).
- Straw
- Plasticine or hot glue
- Vinegar 9%
- Baking soda
- Cloth
- A sharp object (such as scissors)
- A large container of water or a puddle.

🔻 Here's how to do it:
With a sharp object, make a small hole for the straw in the top of the bottle. Insert the straw into it and seal the gap with plasticine or hot glue.
Pour 80-100 ml of vinegar into the bottle. Put 2 tsp. of baking soda on a small napkin and twist its edges. Tilt the bottle and place the napkin with baking soda in it so that it rests on the straw and does not touch the vinegar. Carefully screw the lid on. Our boat is ready!

Shake the boat to mix the contents, and place it on the surface of the water so that the free end of the straw is under the water. The boat picks up speed and sails away!
You need to increase the amount of ingredients and the size of the bottle to launch a faster boat.

🔻 What happens?
The acid reacts with the baking soda. This reaction results in new substances: water, a certain kind of salt and carbon dioxide.
The carbon dioxide leaves the bottles through the straw, and it rushes off in the opposite direction.
