Scientist of the Week- Rocket Balloon
Our scientist showed us how a balloon could fly straight on a string. She used string, a balloon, a straw, and tape. She put the string through the straw. Then, she tied the string to something. She taped the balloon to the straw. Then she blew up the balloon. Finally, she let the ballon go and it took off like a rocket!
