Hi, I'm Lindsay.

And I'm Marshall. Welcome to Tumble, the show where we explore stories of science discovered.

Today we're talking about invisibility cloaks.

Visibility cloaks. Finally you're going to find out how the Romulans cloak their ships, not even the Federation knows that.

I'm assuming you're talking about Star Trek.

Yep. And I think, you know, that's just science fiction.

But Sarah, our associate producer, tells me there's very real science behind trying to make invisibility cloaks a reality.

Generally sure.
