Hey everybody! Spring is springing all around us here in the Northern Hemisphere,

and what better way to celebrate nice weather than by playing hooky from work.

And that is exactly what we're doing here at SciShow Tangents, so there's no new episodes this week.

But here is a rerun about flowers, so you can be primed and ready to wow your friends with

science facts the next time you walk by a blooming garden. See you next week!

Hello and welcome to SciShow Tangents, the lightly competitive knowledge showcase.

I'm your host Hank Green, and joining me as always is Science Expert,

Siri Riley. Siri, how science do in this week?

I haven't actually read any reputable sources,

but I think science got the big boat out from when I was stuck.

Sure, I bet science was involved in the boat.

Yeah, well science is involved in everything.

That's the point. It was like a big old shovel that got the boat out.

I haven't investigated how they got the boat out yet, which I do feel a little bad about.

I learned a new word though, which is reflote.

Is it just when you make something float again after it's no longer floating?

Apparently it is specifically to do with big boats that when they stop floating,

the process of refloting them where you have to try and do a bunch of things at the same time

to get them not touching the ground anymore.

That sounds very sciencey. Like you have to dig in the right spot,

you have to push in the right spot.

And then you also have to do like, they can tilt the ship with things that they have on the ship.
