Method to get a box over a 65mm tall 'wall'?

Question

I'm currently doing my school project on design and invention. I need ideas from you guys...

My problem is to come up with a method in getting a box (size of the box is about 400mm cubic) over a wall with height of 65mm. Any electronics devices or method can be used. However, everything (device and box) must be on the other side of the wall as to comply to the given rule. Any idea from you guys is greatly appreciated.

P/s : the length of the wall is 1.2m.

Thanks a lot...

Answer 1

Lever and fulcrum.
A 1.5 m high pole as fulcrum, and 1.5m pole attached as lever on top to form a T shape, it must somehow be freely moving but not detachable. Position it on other side of the wall to the box. Tie rope to box and to end of lever. Lift box over the wall.

If you are allowed to use any electronic device, you could also use your phone to ring a removalist to come and lift the box over the wall for you.
