Ball In Cylinder 1
"The Ball in Cylinder No1 Puzzle ... is my second mechanical puzzle design. I feel it is way much better than my first (the RevoLUTION Ball Puzzle), not only in terms of the different trick involved but also more aesthetically pleasing. The object is to remove the hidden ball bearing inside the cylinder.
After 3 prototypes, I finally got the metal fabricator to produce a small quantity of units. The puzzle is made entirely out of 6061 aluminium. I am very happy with the outcome." -Jerry Loo
