I need to build a barge out of aluminum foil and put pennys in it without sinking...any ideas on howto makeit?

Question

^^^^^^^^^

Answer 1

Materials: 90 cm Aluminum foil,120 cm masking tape,  Pennies,To build a barge that will float the most pennies without sinking. Pennies will be added until the barge sinks.

The Aluminum Foil Penny Barge The purpose: of this event is to create a floating barge made from one square foot of Reynold’s Wrap Aluminum Foil (Regular), and fill it with as many  pennies as possible, before it sinks.in this link you can ask them and they will answer back your question,here is the link,http://www.omsi.edu/explore/whatzit/answ...

Answer 2

build your barge in a cone shape. the pennies on the bottom provide weight for stability just remember that if the barge is to be pulled to build the end toward the pulling vessel slightly higher to avoid water intrusion. actual construction is easy just role the foil to build a cone of the desired size.  then secure it with a little tape. it will both work and win for originality.

Answer 3

Why is this in the Alternative Science section? It seems pretty legitimate to me.

Answer 4

Seriously, don't listen to these other people.  Especially the cone guy.  Look up Viking ships and mimic that design.  That is your best bet for stability and holding capacity.  It is the leaf shape that does it.  It is tried and tested by hundreds of Viking soldiers, as well as modern boat builders.  If you take a look at Asian ships, like Thai, Chinese, or Vietnamese you will see the same leaf-like design.  It really does work.  Happy boat building!

Answer 5

paste or insert a thermocol sheet, at the bottom. No one will identify.

Answer 6

All good ideas.  You need to make the "cargo" area pretty wide.  Use the least amount of glue and tape as you can, as it will weigh down the boat.  Make sure the sides are high enough so water doesn't come aboard and sink it.  Just make a few models first and see which one work the best.

Answer 7

If you wanted to be really precise about it all, you would calculate the weight of the pennies to be added, and then design the barge to displace the appropriate amount of water needed to cause that buoyant force.....

Otherwise, I would just build a box like structure with a secure deck.

Answer 8

In addition to all the other answers, (very good ones!) try a version with a bottom that traps air underneath it. It may be unstable, but if you can manage it, it will help hold up the weight of the pennies better.
