Don't open gmail. You would be confused Only read this:- Note: i m really not demotivating ur idea. Plz thrust me But i have a problem in ur idea Ur idea will lose its(i mean magnet's) magnetic properties. It will no further be able to attract the tank towards it. I have no objection towards ur idea, but only 1 i.e. the upper one(what i have written).

Hey kostya, Just forget about all the mail what i said to u Read the last mail and don't waste ur time on reading the previous mail

Next update: Adding magnetic field U can experience this by passing the tank between the 2 magnets after the update
