Emma and Johnny had a blast with this simple boat-building activity at the Acton Discovery Museums. They were each given a roughly 6-inch by 6-inch sheet of aluminum foil, which they shaped into a boat. Then they tested how many pennies their boats could hold, first in tap water and then in salt water. They learned that wider boats held more pennies than narrow ones, so long as the pennies were spread out evenly on the wide boats. They also discovered that their boats held more pennies in salt water – but only if they were careful to not let any water into the boats when they set them in the bin!
