I bought a 50X play microscope for kids at zellers for $20 it worked well it has a spacer at the end with a light so you can hold it at the right distance. It's bigger than the one above and its purple.

I will not play at tug o' war.
I'd rather play at hug o' war,
Where everyone hugs
Instead of tugs,
Where everyone giggles
And rolls on the rug,
Where everyone kisses,
And everyone grins,
And everyone cuddles,
And everyone wins.
