If you don't know what a Hafthohlladung click here: http://en.wikipedia.org/wiki/Hafthohlladung
and here: http://www.youtube.com/watch?v=Rq5edjlhcaQ
I took one of my Dragon 1/18 Hafthohlladungs and put a little magnet in between the 3 prongs, such that it just barely protrudes. I got the magnet from a magnetic chess game piece.
Once i tested to make sure it would adhere firmly to a metal surface i glued the little magnet in place. But andrew, you're saying, how can this thing stick to a plastic tank model?
Well, the next step was to remove the hull top from my T-34 and to the inside of the upper hull sides i glued several flat pieces of tin in various locations. The magnetic attraction from the little magnet is strong enough to hold it firmly to the tank's hull, even through the plastic.
So now, my brave little 1/18 panzer grenadier can run up to my unsuspecting t-34, stick his Hafthohlladung to the hull and then run. And he'd better because 7.5 seconds later BOOM! I placed a small digital recorder inside the tank. When i put the Hafthohlladung onto the tank i also push a secret button which activates the tape recorder which has an explosion sound recorded on it with a 7.5 second delay. 7.5 seconds was the delay on the real Hafthohlladung's fuse, if you hadn't guessed that already.
The beauty is i can use my t-34 as a regular t-34 still. It is completely unmodified externally but now it's also magnetic.
very cool
