Gelli Baff ''Goo'' Powder Experiment

Watch in amazement as this easy to mix powder expands to make a coloured, thick, "goo" material.

When the fun is over, cleaning up couldn’t be easier! simply add the dissolver sachet to the goo and watch it turn back into water. The powder soaks up to 400 times its weight in water.

Great for use in Early Years establishments or for learning about changing materials in Primary Schools, use under adult supervision after appropriate risk assessments have been carried out.
