Dry Ice Boat 1

Dry Ice Boat

Dry Ice Boat Science EperimentDry Ice Boat is an experiment where kids can power a boat without any gears or propellers. It’s a simple way to make a boat with few materials and propel it with dry ice. So, let’s build it and get ready to sail!

Safety First! Adult Supervision Required. Don’t Eat/Drink your Experiments, Wear safety goggles where ever required

What to Do!

  1. Pour water into the tray.
  2. Pour some green and red food color into the tray.
  3. Mix the colors to get a dark color
  4. Using a hammer, break the dry ice into small pieces.
  5. Pick a small piece of dry ice with at least one smooth surface. ( Make sure it has one smooth surface if you want a whirlpool)
  6. Drop these flakes into the tray and it forms whirlpools.
  7. Using a marker, mark two lines from each end of the pipette at 0.5 ml and 3 ml marking.
  8. Cut along the marked lines.
  9. Make small cuts on the boarder side of part B
  10. Put some dry ice flakes into part A of the body.
  11. Using a pipette, add some water into part A.
  12. Insert part B into part A.
  13. Place it in the tray.

Working Principle of Dry Ice Boat :

In this experiment, we power a boat using dry ice. We add water into one part which has dry ice in it. The dry ice starts to sublime once water is added to it. It produces carbon dioxide gas. Once the second part is inserted into the first one, there is a small outlet for the gas to come out. When we place the boat in the water, the boat moves forward due to the gas that’s going out.

This experiment follows newton’s third law – “Every action has an equal and opposite reaction.”

The gas going backwards makes the boat sail forward. So, now you have a boat powered by carbon dioxide gas.
