Hands-on Science Fun with Balloon Boats

7:22 PM



I saw these a while ago on A Little Learning for Two and have been waiting for the right time to try it. Since we were already on the subject of transportation this week I figured this would be a good time!

Supplies for a Balloon Boat






How to Assemble a Balloon Powered Boat


We started with a mushroom container that had low sides and flat bottoms. I figured they would be pretty stable.

I used a hole punch to make a hole in one of the short sides of each boat.


Then I took a balloon and rubber banded it onto a straw,




I stuck the straw through the hole in the boat with the balloon on the inside of the boat.


Then I hot glued around it on both sides. Excuse the poor glue job; it was hard for me to get around the straw!


Once they were dry, I filled the pool up a little, and we headed outside to try them out.  At first, I blew up the balloons and the girls took them, holding the straws tightly, and released them in the water. 

They enjoyed watching them zoom off.



It did take them a little while to figure out that the air from the balloon was what was making the boats move.


My oldest even figured out how to blow up her own balloon! 



I hadn't bothered to blow the pool up completely before filling it figuring we would just put it away after this. 

But this was much too inviting, and before I knew it, they were all in! Splashing and zooming their boats across the pool.
