Fun With Science: DIY Speakers, Disappearing Glass & More!


Science Ninja Anthony Morgan stopped by the studio to show us some fun and easy science experiments you can do at home with your kids. Because remember: science is everwhere.

DIY Speakers

This is a quick and simple way to make speakers for your smartphone in a pinch. Perfect for kids, camping and barbecues!


What you’ll need:

  • 1 cardboard tube
  • 2 plastic cups
  • 1 marker for tracing
  • a blade or scissors


  1. Cut holes for your paper tube into the side of the cups, and a small hole along the side of the tube for your smartphone.
  2. Pop your phone in and enjoy the beats!

Disappearing Glass

This one is a great optical illusion demonstration to do with kids or friends using simple materials from your kitchen.


What you’ll need:

  • 2 or 3 Pyrex beakers or bowls
  • 2 L bottle of vegetable oil
  • latex or rubber gloves
  • a towel (for clean up!)


  1. Place your small beaker or bowl into a bigger beaker or bowl.
  2. Pour the vegetable oil into the large beaker and watch the small one disappear!

Dancing Cornstarch

Teach your teenager about sound waves, vibrations and non-Neutonian substances using everyday household items.


What you’ll need:

  • 1 box of corn starch (16oz)
  • a pitcher of water
  • plastic wrap
  • a speaker
  • food colouring


  1. Add food colouring and water to a bowl.
  2. Mix in cornstarch, stirring until you have a thick, tacky fluid (it should be difficult to move a fork or spoon through the solution).
  3. Wrap your speaker in plastic.
  4. Pump up the volume, adding the cornstarch solution bit by bit, and watch your cornstarch monster dance!
