Harry spent a long time making a cog wall
There were some great little models in the 'mechanicals' section. They all used a variety of levers, ratchets and cogs and moved really smoothly when the button was pressed.
The water areas were very popular. There were pipeways and mini 'canals'
Peter built some really great towers, taller than him and was actually applauded by the stunned ladies in the background of the photo! He was very proud, then gave it a big kick to knock it over!
Peter loved this strong fan blowing a ball up into the air
These tubes were filled with different liquids to show how the thickness of the liquid affects the speed at which a ball travels down the tube
These two bottles contained water which, when swirled while falling into the bottle underneath, created a really impressive whirlpool
The spinning tables were visited several times
