how to make a boat out of aluminum foil

Understanding how a boat floats on the water and exactly how weight distribution affects it is important for every boater.

In this article, we’ll take a look at how to make a boat out of aluminum foil and observe the effect of weight distribution on it. This is a fun activity for kids and boaters alike to understand how boats work.

  • A few dozen coins
  • Liquid container
  • Water
  • Scissors
  • Ruler
  • Tape (optional)

Aluminum Foil Boat Activity


1. Prepare the materials

Prepare square sheets of aluminum foil, preferably in a few different sizes to be able to test out just how the size of a boat affects buoyancy. Get 4×4 and 8×8 inch sheets for starters.

For the liquid container, it would be best to use a fish tank or any transparent container to be able to see how much the aluminum foil boat sinks. Fill this box with water; note that it doesn’t need to become filled to the brim. Several inches deep will be enough.

Our boat’s cargo can be anything, but coins are ideal because it will end up being easier to simulate situations where weight concentration is limited to specific points. Marbles are also a popular choice, though we cannot stack them. The important thing is usually that the objects used should have the same size and weight.

2. Make the boat

Next is definitely to make an aluminum foil vessel. The idea is to make the boat using one square sheet without needing to further cut or use smaller parts to add uniformity. Feel free to use any design, but those with more surface area for the particular load are preferred.

Make boats associated with differing sizes and designs to see what changes. Here, we have a simple boat to get you started; it can be similar to a folded paper boat.

Aluminum foil boat instructions:

  • Fold the foil sheet in half. With one side of the sheet facing you, take the outer edge of this and fold the evade towards the middle line you just created. Do the same on the other side.
  • Unfold one third of the sheet. Change the sheet’s orientation to resemble a diamond with loose foil leaves at the corners.
  • Collapse the sheet in half, making sure the loose corners are folded towards each other. At this point, you should have a shape resembling a boat.
  • Continue molding the edges of the sheet so the boat has curves.

3. Set the boat on the particular water

This activity normally involves setting aluminum foil sheets with different forms on water as well, not just boats. These include an unfolded sheet and even a crumpled one. The objective is to observe how each floats differently.

When it comes to the boat, we will put some load onto it after setting it on the water. Coins simulate having passengers or cargo on a boat because we can stack them to vary weight submission.

Lay down coins on the boat, but distribute them evenly across the boat’s surface. We’ll see how the boat starts sinking as the load gets heavier. Once the particular water gets into the motorboat, however, it will sink completely.

If a person stack the coins together on the boat, this will sink even if the number of coins is fewer compared in order to when they were evenly distributed. This demonstrates what happens when we keep too many things on a single point from the ship.

Additional Information


1. Can you make a full-sized aluminum evade boat that can hold passengers?

It is unrealistic to make an aluminum foil boat that can keep a person, even the child. This is because the material would give in and tear from the weight. The closest we can do is to make a boat frame made of different materials and then cover that with aluminium foil.

2. What some other variations can be applied when you build a boat out of aluminum evade?

One design variety to try is to make a deeper hull, which would allow the boat to sink lower into the drinking water without capsizing. You may also try reinforcing the boat structure using tape or more foil linens to counteract the boat’s warping when the weight increases.

3. What is certainly demonstrated by this activity?

When you make an light weight aluminum foil boat, the exercise demonstrates the concept of buoyancy plus density as well as shows the particular importance of managing a boat’s weight. By increasing the load, we can observe that the boat’s density changes and that it will sink once this reaches the point where its denseness has exceeded the density of water.

However, it is also important in order to note that a vessel itself has weight, and this should be included within any calculation for fill capacity.

4. Can I use tin foil with regard to this activity instead of aluminum foil?

Aluminum foil and tin foil are two similar but different things, but for this action, the difference is negligible. Feel free to make use of tin foil if a person prefer, though it is worth noting that aluminum foil is a slightly softer material.


We’ve gone over the activity that demonstrates how vessels float on the water, including instructions for making an aluminium foil boat. We’ve covered how to vary the distribution of weight and how this can be used to simulate the particular load on a motorboat. Now you have a better understanding of boat denseness.
