Class 5's blacklight experiment

This morning class 5 tried out an experiment Ms Becky discovered on the weekend. The aim was to transform a regular flashlight into a 'blacklight' which makes whites and fluorescent colours seem to glow!

All we needed was an LED flashlight (like the ones on cell phones!), clear tape, a blue marker and a purple marker.

Here are the steps:

Put down one layer of tape.
Colour it blue.
Add another layer of tape.
Colour it blue.
Add one last layer of tape.
Colour it purple.

We worked as a team to complete all the steps- then it was time to test it out. We were amazed at the way it made the white on our clothing glow! We also loved the pretty blue-ish light it created on other things.

Feel free to try our 'flashlight-hack' at home! It was super fun :)
