What to do:
Gather together all the things that you need for the sight experiment
This experiment is all about sight
First of all, take 2 pencils and hold them straight out in front of you, at arm’s length, with the ends of the pencils facing each other.
Now, try to touch the pencils together. Was that easy?
To try and make it harder, Close one eye. Try to touch the pencils together again.
Did you manage to do it? Try closing the other eye?
