What’s it about?

All submarines use the principle of ‘displacement’ to enable them to dive down in the ocean and come up to the surface again. You can study how this works for yourself, by making your own submarines in the following science experiment:

Topics covered

Pressure, Displacement

What will I need?

  • PLASTIC BOTTLE
  • PLASTIC / RUBBER TUBING
  • MODELLING CLAY
  • WASHERS / WEIGHTS
  • STICKY TAPE

How does it work?

Unfortunately, this section is only available in the e-book version of the project.

This science experiment works because air weighs less than water. When your bottle submarine is filled with air by blowing on the tube, it becomes lighter than water and it rises to the surface. When the bottle submarine is completely filled with water, it dives down because the bottle of water and the weights added to the side is heavier than the water surrounding it.
