Product Details

Make valentine hearts for that special someone! In this lab students create a heart out of polyurethane foam by mixing equal amounts of polyurethane parts A and B. This lightweight foam expands to about 30 times its original liquid volume and will become rigid in about 5 minutes. The hearts can be shaped or colored to suit individual, student preference, combining art and chemistry in a way that will develop your students scientific reasoning skills. Complete for 24 students working in groups of 2.

Note: Adequate ventilation required.
