WARNING: CHOKING HAZARD - Small parts. Not suitable for kids under 3 years old.
Mix two chemicals to create a buoyant polyurethane foam that closely resembles natural pumice.
The set comes with all the materials you need for the activity, along with a real pumice sample.
Using this product is easy. First, gather all the materials included in the set. Then, carefully mix the two chemicals together. As you do, you'll see a polyurethane foam form that's buoyant and looks just like pumice. Remember, this product has small parts, so keep it away from children under 3 to avoid choking hazards. After using, store the remaining materials in a cool, dry place. This will help keep them in good condition for any future experiments.
