DIY magnifying Glass with Telus World of Science

Have you ever wanted to take a closer look at something in nature, but just haven’t had a magnifying glass laying around?

Well on Day 36, we are up to the challenge of changing that.

Our friends at The TELUS World of Science will show you how to make your very own magnifying glass using only a few simple supplies!


2-litre clear plastic bottle with smooth, curved edges

2-piece mason jar lid

A marker (sharpie)


Tape (masking tape is preferable)

Water bottle (full of water)


Apply some masking tape to the bump at the top of the bottle.

Using the flat insert from a mason jar and your marker, trace around the edges of your jar lid.

NOTE: You may need to ask an adult for help with the steps involving the scissors!

Using the scissors, cut into the bottle and cut around the circle, a little bit OUTSIDE your line.  

After your circle is cut out, use the scissors to trim it down to the line you traced. This will help the final circle have a smoother edge and be easier to cut.

Now you can peel off the tape! Place your cut plastic circle into the rim of the mason jar lid, and there you have it, your very own Magnifying glass!
