A copy in plastic of George Hart's IPP28 exchange puzzle from Prague in 2008. FIRE is a screw-together tetrahedron made of two identical plastic parts. The tetrahedron is divided in two along a helicoid surface whose axis is aligned with an axis running from the midpoint of one edge to an opposite edge midpoint. This puzzle is VERY satisfying to play with!
Note that George's original exchange puzzle was produced in nylon. This copy is accurately reproduced in plastic. It is available through Hendrick Haak's puzzle shop in Germany for 20 euros (about $24).
The puzzle is as new. I will include a copy of the solution from the IPP28 exchange booklet.
I
will ship within the US at insured priority mail pricing (around $10),or as a first class package if preferred (a bit less expensive). I am
happy to ship overseas at cost (The minimum cost for an overseas package
is $15.50, not insured), but I cannot always guarantee
that overseas packages can be insured.
Thank you for viewing my auction!
