Kosmos Space bubbles

To do this, fill the rocket base with oil and coloured water according to the instructions and add an effervescent tablet to the mixture - and the fun can begin. In the leaflet, little researchers learn how bubbles are created, why they rise and fall and how the great colour effects are created. This also works in the dark, by the way. Just plug in the LED lamp and the glowing bubble rocket turns into an ingenious lava lamp. The experiments can be repeated as often as the children like. Just watch the bubbles and marvel at the glowing wonder. The perfect gift for children from 8 years with fun guaranteed. Contents: Instructions, rocket lamp consisting of rocket stand, rocket cup and funnel tip, the LED lamp for docking, as well as other experimental material such as pipette, measuring cup, stirring spatula, dye tablets.
