Gelli Baff is quite possibly the greatest innovation in kids bath time technology since Bubble Bath was invented. The idea is simple. Turn a bath of water into a bath of glorious, thick, goo.
You simply run a shallow bath (5-6cm deep), turn off the tap, add a sachet of the gelli baff powder and then all water will magically turn into jelly. When you have finished, there is another sachet of powder to add, which turns all the jelly back to water, so that it can be drained away.
Gelli Baff comes in a range of 4 colours, and costs £4.99 per 300ml box.
