Hamish the scientist

Hamish showed us how to make a tornado in a bottle!  You will need:

• 2 plastic bottles
• a special joiner (which he bought from Te Manawa when he was having a special visit there with his dad).  If you don't have one of these you could experiment with the lids of the bottles - drill holes in them and join the bottles with really strong tape (duct tape).
• water!

1. You put water in one of the bottles then use the special joiner to stick the other bottle on to it upside down.  Make sure it is on tight!  Then turn it so the water is on top.

2. Then you 'swirl' the bottle around... (thanks Mrs Williams for helping!)

3. Soon you will see bubbles forming and you can stop swirling it...

4. Now you have a tornado in the bottle!
