Be a science detective - test of observation skills #5

This video activity is amazing, BUT ONLY IF you ask someone else to give you a hand.

Why? Because clicking on the link below reveals the answer... before it asks the question.

So it spoils the fun, unless you close your eyes and someone else clicks on the link for you, then clicks to start the video for you.

First, turn on the sound on your computer.

Then find a helper willing to

1. wait for you to close your eyes

2. click on the link below

3. REMAIN SILENT

4. see a YouTube video ready to start

5. click on the arrow to start the video

6. tell you to open your eyes

Ready?

CLOSE YOUR EYES before you ask your helper to click on "amazing test of observation skills."
