Create a cash-carrying cargo cruiser!
- Construct a boat out of 1 square foot sheet of aluminum foil.
- Estimate how many pennies your boat will be able to hold.
- Then, float your boat and place as many pennies as you can in the boat before it sinks.
- Was your estimate right?

We did this project at school, and we used a piece of foil that was 10cm by 10cm, and another that was 20cm by 20cm. We used pennies to sink the boat. My 10cm boat held only 12, but my 20cm boat held 79!

It took 2 dollars, 4 quarters, 3 nickels, 5 large hair ties, 12 small hair ties, 3 lip glosses, 3 dimes, 5 pennies, 5 plastic, hair ties, 2 hair clips, 1 bracelet, and 5 metal hair clips for my brother to mack it sink.

i doesn't like the project at first but it turned out to be a great success. We had a design competition and yay our massive ship with the area doesn't like my guess 113 it was 126 pennies. The reason theat we won is because we doesn't use to much paper but we have lots of surface area.

We went to the science lab and made tin foil boats. My boat held 50 pennies, and that is what I guessed.

Hey my name is Maggie! My G. T. class went to the science lab. My large tin foil boat held 11 pennies. I guessed it hold 10 pennies. My guess was very close. It was a sooo cool! I want to do this project again. Thanks!

when I did mine I got it to hold 159 pennies we're doing this projec in tech at school and our school record is 160 which is really close to me and my partners!!!

I had made a aifoil boat that could hold fifty six coins. My boat was a mediem sized boat thats why my boat carryed half of the bucket.
Jake, age 8 of Brisbane wrote:
My boat carryed 17x 5c coin. It would have been better if the alfoil was not ripped. But it did good.
