How to Magnetize WarCry Terrain Walls

How I magnetized my WarCry terrain walls to be completely modular and easy to store/transport.

I apologize for the auto focus, audio, and all around awkwardness. I am a complete noob when it comes to recording/editing video so this is a straight upload from my camera. I assumed while recording that anyone who stumbled upon this video already had some level of experience with Warhammer or wargaming so I may have glossed over a few things. Oh, and any time I say "bearing" I mean "magnet" (derp), this was done entirely off-the-cuff.

A list of what I ended up needing to magnetize the complete set of walls:
Plastic lid (x1)
Scissors
Hobby knife
Hot glue gun
Water
5mm ball magnets (x40)
5mm drill bit
2mm x 1mm round/cylinder magnets (x32)
2mm drill bit
Power drill (optional)

I ended up using super glue to glue the 2mm magnets in after drilling. I probably should have used the 3mm x 2mm magnets in their place but what's done is done. I would not recommend priming prior to doing this. My husband was bored and primed everything before I was able to get to them.

If any kids see this video: please do not use power tools, knives, or hot glue guns without adult supervision.
