Don't tip the ship!

How many marbles will it take to tip the ship?

Today, Josie made an amazing narrow boat model called 'Star Shine' out of a plastic milk bottle, cereal box and tin foil. She used marbles to test how much cargo her boat could carry in a bowl of water before it sunk. Josie found out that it took 14 marbles to make her boat sink to one side and it would have taken another 3 for it to sink completely. She loves her boat so much, she didn't want to sink it (I don't blame you - it is wonderful!)

 Top tip: Josie found that marbles were a bit difficult to use as they rolled around the boat a bit too much. She has decided that next time, she would use cubes as they don't roll. Well done Josie - great thinking!
