Didn’t get eclipse glasses? Here’s a DIY option to safely see the rare event

Forget to get your special glasses for Monday's solar eclipse? Here's how to make a pinhole projector using common household items so you can still observe it.

Monday’s total solar eclipse is a once-in-a-lifetime opportunity that shouldn’t be missed, experts say.

York University astrophysics professor Sarah Rugheimer told Global News another one won’t occur over Toronto and eastern Ontario for another 375 years, until the year 2399.

Experts also warn looking at the sun without special glasses can cause serious and even permanent damage to your eyes.

But if you’ve not yet secured your ISO 12312-2 international standard glasses yet, there is another way to observe the eclipse — with a pinhole projector.

You should not use the projector to look directly at the sun. Instead, you can use it to see an image of the eclipse.

Here’s how to make one, according to NASA.

Gather a cereal or shoebox, a piece of paper, scissors, tape, some aluminum foil and a pen or other object with a point.

Use the pen to trace the bottom of the cereal box onto the piece of paper (or left or right side of the shoebox if you’re holding it as if to open it and access the shoes).
