Torpedo (Pool Toy)

Pool toy - Glides underwater over a couple of meters or more. I use it mainly when teaching scuba diving to children but it's also fun for kids swimming with mask and snorkel.

Kids love to throw this torpedo at one-each-other during scuba diving lessons.
You will need to add some ballast (anything small and heavy will work - avoid stuff which can rust) to make sure that the torpedo's buoyancy is neutral when underwater (i.e. it shouldn't sink or float).  There is a hole at the bottom of the torpedo for that purpose. Once the ballast has been inserted, you should secure it with glue (epoxy works best).

Materials and methods

- Ballast (e.g. old stainless steal nuts and bolts, pieces of lead, etc.)
- Glue (e.g. epoxy resin)
