Fun With Science: DIY Speakers, Disappearing Glass and 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
Instructions:

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!)
Instructions:

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
Instructions:

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!
