This is a great way to get young girls interested in science. (We all know that research indicates girls become less interested in math and science at puberty) So, what could be better than Spa Science? Girls can relax and experiment with many fragrances in their bath and it is real chemistry. They perform experiments with unbreakable, safe test tubes while learning the secret behind the chemical reaction of foaming and frothing baths.

While smelling the potions and conducting science experiments they can see how scents affect our alertness, moods and memories. Then they can compare the responses of siblings, parents and friends making this a shared adventure the entire family will enjoy.
