The 2nd & 3rd classes find out how to switch the
shower on and off - just by opening and closing the screw cap.
We made a shower to show the power of Air Pressure.
We got a bottle and put four holes in it with a thumbtack.
Then we filled it up with water to the neck.
We put food colouring in it for fun. We screwed the lid on tight.
If we open it a little, the water comes out like a mini shower
and when we close it, the water stops coming out. Wow!
