Climbing Rainbow
Picture 1

You will need: 

  • Sandwich sized plastic food container
  • Markers
  • A small wooden dowel or pencil
  • Paper towels
  • Scissors
  • Tape
  • Water


What to do

1. Cut a strip of paper towel

2. On a short edge, use markers to make a strip of blocks in the colors of the rainbow.

3. Tape the top of the paper towel to a vertical surface and put only one end in the dish.

4. Gently pour water into the bottom of the container and watch what happens!


As the paper towel absorbs the water, the capillary action will carry the water along with the marker ink up the paper towel. After the colours climb up or meet in the middle, you have your very own rainbow!


Paper Hovercrafts


How it Works:

The pocket under the hovercrafts trap air and create a zone of high pressure. Further, the air moving over the craft has lower pressure. This difference creates lift and gets rid of the friction that normally holds the paper in place on the table. Without friction holding it back, a little breath is all it takes to get the hovercraft speeding on its way!

What melts in the sun?


For this experiment you will need to gather the following things:

  • A bun tin (you could use a normal tray, but it’s nice that the bun holders contain the substances that do melt).
  • Items such as lego,  chocolate, wax crayon, a rubber, ice, marble, paperclip , butter, a candle etc. 



  1. Add your variety of small items to your bun tin.
  2. Make sure the sun is shining (the hotter the day the better) and place your muffin tin outdoors in direct sunlight. 
  3. With your grown up,  think about which will melt and which ones won’t.
  4. Leave in the sunshine for a while.
  5. Check by to see if your predictions were correct. Which things have melted a bit, a lot or not at all?
