the ring on wing is a simple toy to make from odds and bits. first you need to make a fan
propeller from an old bottle and you put some ring magnets. and there is a little stick
in the middle. now this is the propeller which will rotate and the ring magnets will rotate.
then make a base, a kind of platform from a box and a card sheet and you put the stick
in this hole in the box. here is a bangle made of steel with a man on it. and the bangle
sticks onto the magnet. now you put the bangle in contact with the magnet and if you place
the whole assembly under the fan, the propeller rotates along with the rotating magnet and
the bangle or the ring rotates and the man goes round and round in a very interesting
manner.
