In one of his most popular videos, engineer and YouTuber Mark Rober visits a primary school armed with a special powder that glows under UV light. He secretly coats a student’s hands and then watches, over the course of the day, as the “germs” spread around the classroom.
When the lights go out and the UV torch comes on, the results are unforgettable – glowing fingerprints on desks, door handles, faces, and food. It’s a brilliant way to show just how easily colds, flu, and stomach bugs can move from one person to another.
That same kind of experiment is easy to recreate with Glow 2 Show Powder. Made in Australia and far more affordable than imported products, it behaves just like the powder Rober used – invisible in normal light, but glowing brightly under UV.
Teachers can sprinkle a little on a surface or one student’s hands, then use a UV torch at the end of the lesson to reveal where it travelled. It’s safe, simple, and an unforgettable way to show how good hygiene helps stop everyday bugs from spreading.
