After initial tests created a series of large holes in the wall of the lab, the higher-power Scanning Tunneling Tennis Ball Microscope project was quickly shut down.

Tennis Balls [Explained]

Transcript Under the Cut

[Cueball fires eight tennis ball at decreasing heights using a tennis ball machine, making four "thunk" noises. Megan is standing behind him.]

[Ten noises come from the right side of the panel.] Bonk Bonk Bonk Bonk Bonk OW! Bonk OW! Bonk Bonk

[Megan has her hand to her chin.] Megan: Ok, there's definitely a person over there. Let's do one more pass to try to measure their height.

[Caption below the panel:] Electrons are small and hard to work with, so some scientists have developed a scanning tennis ball microscope instead.

Colorizing Electron Microscope Photos Deceptively/Incorrectly

Some 'science' photo libraries are…questionable.

This photo claims to be "Ant carrying aphid egg, SEM" colorized to highlight the "egg" but look closely!

It's NOT an egg. That's just part of the ant's mouth! To understand what's wrong, take a look at the second set of photos by Hugo Darras. You can see the "egg" is part of her maxillae, the part she uses to collect liquid.

How did they decide it was an aphid egg?

Most aphids don't even lay eggs...they give live birth!
