Tube It In is a classic design by Wil Strijbos. To solve it you have to
take the various small rectangular pieces and pack them all inside each
other. Wil originally made it with small cut sections of metal pipe!
What an original and fun idea, still unique to this day. The puzzle
itself is moderately tricky and fun to solve.
