Falling Teeter Totter
TUMBLING TOMMIE
This problem is rather unique in its principle of operation and offers at once material for study and investigation. Like that of a circus performer, the combinations must be exactly right or the little fellow may fall on his head. In making the man, first bore the holes thru the block and take care to make them parallel. The openings into the holes from the ends must be in the same plane and made to slide over the rounds of the ladder without friction. The tumbler may be shaped and colored to look like a man. A base may be attached to each end, but on opposite sides of the ladder, so that Tommie may tumble in both directions.
