Children have been playing with aluminium foil boats for many decades. One of the more popular uses for an aluminium foil boat is carrying objects across a bathtub, a birdbath or even a puddle. Kids place everything from action figures to coins and other small objects in these boats and push them across the water from side to side. You and your child can build a boat from aluminium foil in just a couple of minutes and immediately add to bath-time fun.
Lay the aluminium foil on a flat surface and place the three, 18-inch long pieces on top of each other so that the sides of each sheet are aligned perfectly. Use the scissors to cut a line diagonally -- about a 45-degree angle -- from each corner.
Place the pencil at the top of each side of the foil, leaving enough of the pencil sticking out of one end so it can be removed easily, and roll the foil down three turns with the pencil. This creates a curved "hull" on the edges of the boat.
Position the iron in the centre of the foil. Fold the sides of the foil up and around the iron leaving enough room at the top to pull the iron out without tearing the foil.
Remove the iron. Use the duct tape to attach any loose corners together. The aluminium foil boat now should be waterproof and ready to haul cargo.
Be careful applying the duct tape as it can easily tear the aluminium foil.
