I have already made a solar eclipse viewer out of a cereal box, tape, white paper and aluminum foil.
First I cut two holes on the top of the box.
Then I traced the bottom of the cereal box on a blank piece of paper and cut out the traced part. Then I put the cut part in the bottom of box.
Then I taped a piece of aluminum foil to cover one hole. Then I put a hole in the aluminum foil so that the sunlight can go through the hole and I can see the light of the eclipse.
|That is a reflection of the light behind me.|
P.S when I came to school today my friend also brought their viewers to school. So that they can also see the eclipse.
