Have any ideas??????

A recent MIT physics (freshman) extra-credit problem: Given 2 small
rectangular magnets, 2 paper clips, 2 thumb tacks, approx. 5 feet of
wire, a small block of wood (4"X2"X.5") build a DC motor running of 1
1.5V that can at least reach 2600 rpm. The use of glue, tape, etc in
the final product will disqualify you. Only the above mentioned items
can be in the final product. The use of a drill, saw, etc.  in
building the motor is ok.
