Today we made the balloon rocket for our STEM challenge.We managed to make it go four meters. We tried cut the straw shorter to see if it would go further, but it just made it not travel as far and fast as the full straw did. In the end we couldn’t go any further because we didn’t have enough room or enough string. Maybe on a nicer day we could try to make it longer in the garden! It was quite hard to make the rocket because our cats kept trying to eat the string!🤣
