• Watch as this easy-to-mix powder expands into thick, coloured goo, perfect for science experiments. • 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. • Teachers can use this product for demonstrating properties and changes of materials. The gelli baff goo powder experiment lets children observe how the powder expands into a thick, coloured goo. This hands-on activity engages children in science experiments, making learning fun. • This resource can be used to show that dissolving, mixing, and changes of state are reversible. Adding the dissolver sachet turns the goo back into water, illustrating reversible processes clearly. This practical demonstration aids in teaching properties and changes of materials. Additionally, the experiment explores other scientific concepts like absorption and volume expansion. The powder's ability to soak up to 400 times its weight in water makes it ideal for various science projects and activities. Ensure adult supervision and proper risk assessments before use.
