So i've been experimenting with magnets for kitbashing, a new way to attach weapons.

My first success using 20c magnets I got from the hobby shop worked okay, not too bad. Could have been better.

So I went out and got these.

Anyone know much about them? Aside from them being bloody small and bloody powerful (they will work great on TF's) I feel the urge to relocate them from the house down the back yard into the chook house because I fear their strength that much.

Is my fear crazy or should I actually be concerned about their strength in the house? (Given there's all sorts of electronic stuff everywhere)
