Last week we did an awesome experiment with a UVA light - that light is different from the UVB light that comes from the sun (it won't give you sunburn).
We had to write a secret message in vaseline to a buddy and then use the UVA light to help it show up...
 |
| Mrs Johnston helped us read our notes |
 |
| It was sometimes hard to read the whole message |
 |
| I wonder what Bella's said? |
After we wrote with vaseline we tried writing with highlighters on black paper.
We couldn't see the message without the light but then we put it under the UVA light and it showed up... just like magic!
 |
| Wow! I can read that message really well! |
 |
| Harry wrote a funny note to his buddy! |
