How was it made?

First of all, I filled the container with a small amount of vinegar. Then, I put a hole on the cap, just big enough to fit the connecter. After, I put the connecter into the hole and placed some bubblegum around the device, to make sure it won't leak. After, I simply attached a tube to the connecter, then a valve, then another tube. Now, all I need to do make another opening on the other side of the pot so that the hydrogen gas can be released. After, I connected a syringe filled with baking soda to the tube on top of the valve. Finally, I just place it into the boat and press the syringe and it will create enough bubbles to make the boat move.
