I made my own coloured bricks from leftover paint!

Here's how I built my garden railway tunnel using sand, cement and old paint laying round the house.
Step 1: build a lattice to mould the bricks
Step 2: Mix the sand, cement and paint and add to the mould
Step 3: Let it dry and remove the bricks
Step 4: Build the tunnel and run some trains in the garden!
