The Wine Klein which we offer in the Grand Illusions Toy Shop is a non-orientable surface, where there is no distinction between inside and outside. It also makes it tricky to clean the inside, so rather than using it for, say, red wine, Tim keeps items like fennel seeds inside.
The bottle opener AND counter is a clever design from Sweden. Every time you open a bottle of beer, the dial clicks around by 1 digit, so at the end, you know how many bottles you have opened!
The metal spoon with a knot tied in the handle is more of a novelty item, but it might be handy if you wanted to remind yourself of something.
Finally Tim demonstrates a trick that we think was discovered in Spain. If you take a drink can, and empty it to just the right point, it will balance on the bevel at the bottom of the tin. Most strange to see, for people that have not come across the trick.
