A truly innovative method to demonstrate micro-organisms at work.
Simply follow a 3 step process to use the gel to its best effect. This bottle is enough to show the effect to a class of 30.
1. Ask the student to rub the gel on their hands.
2. The students wash and dry their hands as normal.
3. When placed under a UV lamp any areas not washed properly will show up - as if by magic!
