0 Guest Posted March 13, 2008 Report Share Posted March 13, 2008 can we assume the coin is also round? or is solid and not paper? Quote Link to comment Share on other sites More sharing options...

0 Guest Posted March 13, 2008 Report Share Posted March 13, 2008 can u explain how twisting the paper will allow you to do this? Quote Link to comment Share on other sites More sharing options...
0 Guest Posted March 13, 2008 Report Share Posted March 13, 2008 Well, I don't have what I need to try it, but I think if you bend the paper a little into a mobius shape, you might be able to slide a coin through it. Anyone able to test this? Quote Link to comment Share on other sites More sharing options...
0 Guest Posted March 13, 2008 Report Share Posted March 13, 2008 I think you can fold it in half then open out a little the diameter orf the semi circle so it seems to stretch/gape at the 15mm part. like the straight part of D would stretch Quote Link to comment Share on other sites More sharing options...

0 Guest Posted March 14, 2008 Report Share Posted March 14, 2008 the hole has a circumference of 9.4 cm fold the paper in half and you have a semi-circle with a circumference of 4.7 cm if you bend the paper so that the circumference is in a straight line, than the coin will slip through with 0.7 cm to spare Quote Link to comment Share on other sites More sharing options...
