My dad was a mechanical engineer and machinist. He loved making hot air engines. If he was alive I would send this to him and I’m sure he would make a little Sterling engine like this one. I really enjoy your videos. The hacks and gadgets are always fun to see.

[m.w.]

Liquid motion toys of the 90's need to make a comeback. Those things were so much fun.

Had you not ever seen sand art like that? They were all over the place when I was a kid in the 80s, mostly in doctor’s offices.

[ClarenceRossAlt]

5:28 Yes, make one about small engines, that would be cool

[FriedShrimpPoBoy]

Everyone of these items would have been seen in a Sharper Image catalog in the 80s.

The Sterling engine should work on either a cup of hot coffee or a cup of ice water. Try it.

That 23, 5° angle isn't random, it's the rotation angle of the earth relative to it's orbital plane.

The Stirling engine is actually a great little thing, there are many options on all sorts of online shops, will probably get one as a gift for my grandma!

[John_Smith_Dumfugg]

Good timing Dave, considering all our computers are down 😂

I like the Stirling engine because it's a simple but elegant design. It's also a great way to learn about thermodynamics and the way energy can be converted from one form to another. It's also a very practical device, as it can be used to power small machines and devices. Plus, it's just a fun project to work on

I used to watch this guy as a kid so happy to see he's still around and still getting alot of views much deserved ❤

[coggy]

I hope this man gets paid well for these promotions =D

[A.L.LGaming]

Nobody gon point out how good his hand writing is, it looks really good to me

Really nifty items - The sand one, I think watching it would put me to sleep rather than distract me LOL. I love it. Thank you Dave 😊

[GoofyAhhGibia]

Dave the first gadget can also be used by not rotating it all the way upside down and instead at an angle so more of the sand is in the water, but can still move down. This way it moves much quicker!

been watching since 2016 and i never got bored. you always get what the title or the thumbnail says :)

[Thuydoan]

This guy makes me smile everyday. Love you, Dave!

[pieflavoredpie]

I used to binge watch you years ago and I’m still glad you’re still kicking

That little steam engine is definitely a nice piece, but certainly for a private workspace. If people think noisy keyboards are bad, imagine that thing next door.
