UV Light Detecting Beads
Science Trick

This quick and easy science "trick" is spectacular and uses inexpensive materials available online or from your local science shop.
Remember, it's always a good idea to practice at home first!

Suggested Materials:

* Ultraviolet light detecting beads in various colours (available online or from your local science shop)
* Thin elastic to thread through the beads to make a bracelet

Suggested Instructions:

Step 1: At home, thread your beads onto your elastic to make a bracelet small enough to fit a child's wrist. You must do this indoors and away from sunlight.

Step 2: Tie a firm knot in your elastic and place the bracelet on your wrist. At this stage, all your beads will be white.

Step 3: Walk outside and expose your bracelet to sunlight. Watch the rainbow of colours that appear when your UV light detecting beads catch some sun.

Step 4: At school, repeat Step 1 to Step 3.......OR take in a pre-prepared bracelet in a container so that it doesn't absorb any sunlight on the way to school.
