Keep the kids organised in the school holidays (or for a great stocking filler for you know when) with this great scientific kit!
This quick to make set of 2 bracelets in this kit are ideal for boys and girls to teach them the effects of the sun.
The white beads are UV beads, and when they wear them in the sun, they change colour to dark blues, orange, purple, yellow, red. The more UV rays, the darker they turn.
Once inside again, they turn back to white. The beads change something like 100,000 times in their life span.
Thread the beads onto the provided elastic and tie up in 3 knots. That's all there is to it! (Instructions provided in the kits.). Good quality wood beads are in the kit to use as spacers.
Save arguments with the kids when it's time to slip slop slap in the strong Australian (or anywhere) sun! If they wear the bracelet outside and the colours turn ... they need sunscreen. Let them argue with the bracelet and not you !
Kit makes 2 bracelets, 1 dark wood, 1 light wood. UV beads are packed in random colours.
