Tongue Twister Sweets
You may have heard of that party trick where someone pops the stalk from a cherry into their mouth, and using only their tongue and their teeth, ties a knot in the stalk.
Well, these Japanese sweets are based around the same idea. There are 3 designs of sweet in the box, and you also get a small mirror included, presumably to you can inspect 'work in progress.'
Obviously you can't take too long, or the sweets simply dissolve!
We don't understand any of the instructions, which are all in Japanese, but you can visit their web site.
The exercises start with simple shapes, based on just one sweet, and build up through increasing levels of complexity.
