This video contains:
0:03 👉🏻 Impossible Nail: Not impossible, but creating this does depend on the use of some amazing physical properties of wood. I won’t reveal the method here but a quick search on NLfast produces a few how-to videos showing the process. The nice version of this puzzle featured here is from @emvz.creations
(mechanics, physics, engineering, STEM, puzzle, science)
0:36 👉🏻 Impossible Bolt: Not impossible- but carefully engineered and machined. This puzzling curiosity was inverted by Scott Eliott and machined in solid brass by puzzle crafters Steve Nicholls and Ali Morris of TwoBrassMonkeys.
1:57 👉🏻 Impossible Jar with Golf Ball: The puzzle aspect is to consider how this object was produced. This incredible piece was made by craftsman and artist Nathan Nickerson, and comes with the golf tee display stand (a nice touch!)
2:27 👉🏻 Impossible Bottle Sculpture Puzzle: The puzzle aspect is to consider how the bottle was produced (I personally have some theories- but I do not know the secrets of this artist). I can tell you with high certainty that the bottle was never cut or altered in anyway, and it was not somehow formed around the objects. This bottle by Phil Evans is one of the best I’ve seen.
3:10 👉🏻 Forks and Toothpick Balance: Incredible DIY physics toy.
(bartrick, balance, centerofmass, equilibrium, physicstoy, stability, fork)
3:38 👉🏻 Impossible Dovetail
(impossiblebox, dovetail, dovetailjoint, impossibleobject)
4:22 👉🏻 Four Marble Puzzle: one of my favorite physics brain teasers- A beautiful and well-made puzzle from Creative Crafthouse.
(brainteaser, marbles, centripetal, centrifugal, rotation, kineticenergy)
4:45 👉🏻 Impossible Arrow: Not impossible, but creating this does depend on the use of some obscure physical properties of wood (similar to the impossible nail). This delightful design was made by illusionist and artist Victoria Skye @vicskye
5:20 👉🏻 Impossible Wallet
6:08 👉🏻 Impossible Knot: how did this overhand knot get into this closed continuous band of rubber? It did not get there by cutting the loop, tying a knot, and rejoining it. Amazingly this band was once a rubber o-ring. How was it cut to produce a knot? An “impossible object” related to the Möbius strip by mathematician and artist George Hart- a brain teaser puzzle he calls “Tying the Knot”.
6:46 👉🏻 Raketti Puzzle
Nova Plexus Puzzle: 12 identical brass rods can create 4 interlocking triangles in a perfect symmetry- look carefully and you can see that each rod is in an identical configuration with the 5 others that connect with it. Precision machined notches on the ends of the rods allow them to interlock with elastic tension such that vector sum of the 5 forces on each rod is zero- creating this astonishing geometry as the equilibrium state. Unlock the ends of any two rods and the system instantly disassembles. Invented and designed by artist and computer scientist Geoff Wyvill in 1978, this puzzle has just recently been made available for sale with a limited production run.
