Alka Seltzer Powered Bathtub Boat

Step 3Use the boat

Use the boat
Insert the capped film canister into the opening for it in the boat's hull while holding the hull vertical. When ready to use, turn the hull horizontal and place it into water. The water inside the canister will come into contact with the Alka Seltzer and begin making bubbles. The bubbles will travel through the tube and move the boat forward until the Alka Seltzer is fully dissolved.

I would like to say my daughter won the challenge at her school. She was too young and small to insert the Alka Seltzer reliably after arriving at school. So, she had to walk about three blocks to school and the water in the canister came into contact with the tablet before she arrived. But, it worked well when we tested it at home. She is an adult now. But, she wrote me a nice thank you on tablet paper, which note I still treasure.
