Foil Boat Challenge
You need
- Aluminum foil squares
- A tub of water
- Pennies or pebbles
Let's play
- Fold a piece of foil into a boat shape.
- Float it in the tub.
- Add pennies one at a time. How many can it hold before it sinks?
- Squash the foil into a ball. Does it float now? Then build a better boat!
Grown-up tip: Small coins are a choking hazard; stay close with little ones.
