SUNSCREEN SAFETY

Although the summer holidays have not arrived yet the weather is amazing so I thought it would be a good idea just to remind everyone about keeping safe in the sun.

Here's an extract from a previous summer snippet  in 2015 all about sunscreen.

Here is a simple and really fun way to test out your suncream.

These little beads are UV reactive and now you can buy them all over the place.


We have been using them for a few years to demonstrate modern reactive materials along with hydrochromic and thermochromic products.

simple bracelets of UV reactive beads

By exposing the beads to UV you can change their colour from a plain creamy white to a range of brights.

Here we have made simple stretchy bracelets and put part in a clear plastic bag which we then smeared with suncream. The other part we left out in the sunlight.
We used two different SPF strengths - it really does make a difference what strength you use!
