Someone gave me this interesting gift the other day. it is 3 balls, each slightly smaller than a table tennis ball. two of them are attached by a piece of string just over a metre long and the third slides up and down said string. if you tug one of the end balls with the others hanging they start to orbit aroung each other and can pull some funky little tricks. :P ANYWAY does anyone know the name for these things (i'll try and get hold of a Photo to post up) Another friend of mine has seen some plastic high tech ones in a toyshop with the name 'Aerojax' this is just a brandname though and I wondered if anybody is familiar with what i'm yakking about.
