Build a boat out of 4 x 4 inch piece of aluminum foil and see how many pennies your boat can hold.
- Form the aluminium foil into a boat shape.
- Place it in a bowl of water and be sure it floats.
- Gently place pennies (one at a time) into your boat. Count the number of pennies it will hold before it sinks
- Then reshape your boat to see if you can get it to hold more pennies than your first try. Remember to be gentle and dry your boat out each time.
You are building off of an idea called Archimede's principal that was developed over 2,000 years ago.
