I will go first, a stealth tank

A rifle scope that can see through walls.

But cannot see through air.

You win

It has a negative magnification: it’s a fisheye lens.

My personal winner

Fisheye lens is fractional magnification, negative magnification is mirror

Thanks for the correction!

It only works if it’s pointed toward Chernobyl

Granted. The scope can see though a wall after you penetrate it with bullets.

You can see through more than walls, you can see through everything! …so all you can see is the empty void

Rifle can’t shoot through walls.
