Make an underwater viewer

Make an underwater viewer

Look underneath the surface

What's going on underwater? Sometimes it's hard to see when you're peering in from the outside.

You can make an underwater viewer to see what's really going on under the surface.

What you need:

  • Plastic tube or plastic milk carton
  • Cling film or other clear plastic
  • Scissors
  • Elastic band

How to:

Be very careful around water . Always make sure someone knows where you are.

  1. If you're using a milk carton, cut the top and bottom off. Make sure there are no sharp ends. If you're using a plastic tube, it should already have the top and bottom cut off.
  2. Stretch cling film or clear plastic tightly over one end of the milk carton or tube.
  3. Attach the cling film with an elastic band. Make sure it is watertight.
  4. Find a pond or lake that you can look at. Put cling film covered end under the water and look through the other end. What can you see?

With your underwater viewer you can look under the surface without getting your face wet!

Try looking at different areas of the pond or lake. Can you see different things in each part? What animals can you see?
