So much fun... pop them, twist them, stretch them, squash them, make shapes, connect the ends together to make circles or connect them to others.
Pull them outwards make a noise then push them inwards again and listen to the sound go from low to high.
Let your imagination free... lots of fun to be had... a hit with the kids!
Colour chosen at random.
