Step 15: Add the magnet

Wedge the magnet in with some wood and PVA glue.

Then with the ball stuck next to the magnet, put layer 6 on top and check that you can free the ball from the magnet with a shake. If not, try packing the magnet out a bit with some waste material.

Make sure you can free the ball from the magnet with a knock or a shake before gluing on layer 6!
