Today our scientist showed us how to make a rocket balloon. He used string, a balloon, 2 chairs, and a straw. After tying the string to two chairs, he attached the straw to a balloon. Then, he blew up the balloon, held it at the end of the string, made sure that the string was tight, and whoooshhhhh! The balloon whizzed by! Zooommm!
