Sensory drop tubes
These tubes are filled with thick jelly in blue, pink and green. The jelly seeps slowly and spiraling to the bottom. When turned upside down, they offer different ways in which the drops or coloured liquid can fall or rise.
The sets will fascinate and are an ideal source for silent focus, as well as inspiring curiosity, developing creative language and understanding simple scientific principles.
It takes an hour for the liquid to drip all the way down, there will be some small drops dripping for the next 40 minutes but you can barely notice it. Please note, this product has not been designed to measure time.
