This kit provides an exciting and unusual way to investigate the importance of good hand-hygiene. It contains a long-wave ultra-violet (UV) light-box (safe to put hands in), and a bottle of "glitter bug" gel, which glows brightly under UV light. The gel and the light box can be used in conjunction to investigate how easily germs can be spread between people, and to learn how to wash hands properly. The kit also contains laminated posters and teachers' notes with ideas for activities and background information.
