In Science, Year 3 have been creating their our own balloon rockets! We did this by first threading a long piece of string through a straw and tying both ends of the string to sturdy supports. Then, we blew up a balloon and whilst pinching it, taped it to the straw. After that, we let go of the balloon and watched our rocket soar! We also tested whether the length of the straw affected how far the rocket travelled.
