A very visual and appealing switch adpated fibre optic lamp. Each of the tips of the fibre optic strands is lit with a bright blue LED lamp. The base contains sparkly crystal like pieces which change colour in sequence thanks to the lamp contained in the base. It can be used without a reward switch, when it will run through a sequence of colour changes. When activated with a switch the lamp will only light up when the switch is pressed - providing a brilliant cause and effect reward. This item is not a toy and must be used under adult supervision only. Requires 3 x AAA batteries.
