Sun safety is important because it could only take 10 or 15 minutes from the heat from the sun to harm your skin. So that is why you should wear a wide brim hat or a bucket hat and you should put on sunscreen, you should at least put it on 20 minutes before you go outside so it can soak into your skin.
These beads can change color to pink purple and yellow because they contain a chemical that changes the color when you take it away from outside then all the color starts to diserper.
The reason why the yellow color beads aren't pink or purple is because it needs a little more time in the heat outside.
The beads are kind of magic
