The Life Straw

It seems like everyone has one of these. Or at least anyone who did any hiking or other outdoor activities. I have one, I never used it. But I trusted the sale and bought one anyway. Well, being stuck inside has got people doing all sorts of crazy things with their time.

Have you wondered if a life straw works? Wonder no more, a decent test to show that if you really needed one it would actually work.

The mighty engines of the SR-71

There are few airplanes as interesting as the SR-71. For those who don’t know (hopefully not many), it’s the fastest manned air breathing aircraft. That’s a mouthful isn’t it? Basically, like everything humans do, instead of simple “fastest aircraft ever”, we had to come up with a bunch of other criteria to subclass everything.

Anyway, the power of the SR-71 comes from it’s engines. Watching the video above to learn about all the crazy engineering that went into place to get the world’s fastest plane built. The video reminds me of those cutaway books you’d read as a kid. Except now it’s animated and narrated..

Pond Water ion Quarantine

First off, you need a natural pond somewhere near by to try this. If you had a suitable artificial pond you might be able to get somewhere, but it would be much smaller. Man made ponds are meant to be clean and clear. Yes there’s some level of dirtiness in them, but overall, they’re clean and clear. You wouldn’t get all those neat things living in the water.

Depth Charges

I’d say this was quarantine related, but probably not since quarantine wasn’t as in effect a month or so ago. I have to say it’s pretty fun though. Some unnecessary jump cuts in the video, but overall it’s neat.

Kind of makes me want to try it too. Also seems like all the LEGOs are still usable which makes sense given that these are small “depth charges”, and the water should distribute the pressure pretty well.

The Hail Cannon

Did you know about these? I didn’t until cursing around reddit (more so than usual being stuck inside). It’s a Hail Cannon. Apparently it’s useless, but it’s still pretty crazy. Basically a controlled explosion directed upwards to try and break up hail stones before they can fall to the ground. I’m not so sure how well it would work, and the research is inconclusive because the weather is, as always unpredictable.
