What you need:
6 - 8oz cans
8ft of copper tubing
1- saw that can cut copper
1- large can (like an energy drink can)
1-two liter plastic bottle
1- role of duck tape
1- exacto knife
1- round stick about two inches in diameter.


1) Cut a whole in your large energy drink can.
2) Cut the bottom off your 2-liter plastic bottal. Then cut a whole big enough for the energy drink to fit and place it inside.
(this will protect the plastic from melting)
3) Curl flexible copper in to tight rings. It helps to curl it around something, like a thick stick. 
(you want the curls tight and as flat as possible. My pictures later on shows a stray curl sticking up in the air. This is bad as it cause the boat to go in a circle.)
4) Use a whole punched to make two wholes in the plastic bottal. Bend the copper so it fits into the wholes. 
5) Adjust the copper ends so the go at an angle down until they are level with the bottom of the bottle. Then bend them at a 90 degree angle so they are behind the boat but not hanging under it. (you don't want the tubing to drag when you put the boat in the water.) Saw off any extra tubing, making sure both sides are even (or your boat will tip)
6) Cut the bottom and top of 4 8oz aluminum soda cans so they look like tubes.
7) Slice the aluminum "tubes" down one side. Role it out to get a rectangle about the height of the energy can.
(these pieces are again to protect the plastic bottle.)
8) Place aluminium rectangle into the energy can so that it covers half the bottom of the can but sticks up over the plastic bottle. 9) Make reliefs marks in the aluminum and bend the edges of the can around the edges of the plastic bottle. Repeat for other side of boat.
9) Use duck tape to hold sharp edges down and prevent cuts later.
10) Fill the bottom of your boat with rocks (not to heavy). Then cover with another aluminum rectangle doing your best to make a flat surface's.
11) Cut off the bottom of a 8oz soda. Put a small candle in the metal cup and place under copper curls.
12) Screw the cap tightly on to the plastic bottle and duck tape shut. (You can use duck tape to shape the noise of the boat as you want it)
13) Get a stick about a foot long and tape a plastic bottle on each side. (I used duck tape but you could use rope or hot glue)
14)Cut two indents towards the frount of your boat so Your stick fits snuggle in between them.
15) Place the stick in the indents so the bottles are evely spaced on either side of the boat.Use duck tape or hot glue for a secure fit.
the top of the bottles should be facing the front of the boat.
16) Suck water into copper tubing then place boat into bath tub, being careful not to let the water out. 
17) Light the candle and be patient. It takes a min. for the water to warm up. 

Optional - Use the left over plastic from the 2 -liter and cut out a window shape. Cover the edges with duck tape to make a frame that match your sliver boat (or what ever color duck tape you used). You can also decorate your boat with other left over pieces. Like gluing an aluminum Pepsi logo on to the side.

Notes:
The only think I bought personally was the copper tubing. Everything else was left over from Habitat for Humanity builds, including the duck tape. If you wanted to you could use colored duck tape for a different looking boat, you could cover the boat in aluminum or aluminum cans using hot glue instead of tape. You could also just forget about hot glue or duck tape and just leave the haul of the boat plastic although it might not stay together as well.

*WARNING*
Copper tubing is hot when heated. Blow out the candle and wait half an hour before touching the copper. [I burnt my self a couple of times figuring out how long to wait :(]
