I think infinity mirror’s are cool. I want to get a smart gift like that for a friend. But not an infinity mirror. What other cool gift can I order online that’s AS COOL AS an infinity mirror? Preferably 20$ to 50$
I’ll list a few that I like but with no links because I don’t want to use Amazon and most results that I find are limited to EU based shops anyway so not sure if it helps you. But I am sure you’ll be able to look them up
Sand pendulum. Basically a pendulum that draws patterns on very fine sand. If you see them you can probably make one yourself that is even cooler
Double Pendulum, pretty cool to look at
Gyroscopes.
Tensegrity models. Those floating style structures that actually hang
Decorations with magnetic sand or fluid
Splits a beam of white light into different colours, and shines them out diffferent orthogonal faces of a cube.
Looks cool but I had to laugh at this:

If you’re wanting something that makes for a neat, mesmerising visual effect, maybe a plasma ball?

It looks like they’re available on Amazon for the mid-to-low end of that price range.
Those little parabola mirrors that make the toy seem to float above.
Newton’s cradle
Good quality Rubik’s cube
Prism color cube
Magnetic sand hour glass
The drinking bird
Little piece of bismuth was a good gift I gave, small desk ornament or such
RGB LED strip kit. Can use as backlighting for a mirror or tv, and could later be used to make an infinity mirror.
Rock slings are incredibly fun, you can chuck rocks and balls so far people love to try it, especially kids
