People are really going to be really impressed when I bring snatch blocks to the gym.

Kid: "Hey dad, why did you call my sister Rose?"
Destin: "Because mom loves roses"
Kid: "Thanks, dad"
Destin: "No problem, snatch block"

The guy that stopped to help you gave me a big smile too, hands weathered from what must have been a lifetime of physical labor gave and instantly knowing what to do, how to help and taking the time out of his day to stop for a stranger, very respectable and heartwarming.

A rule of thumb we always used for figuring out mechanical advantage for rope rescue systems was, if the pulley (or snatch block) is moving with the load, it is providing a mechanical advantage. If it is not moving with the load (i.e. it is attached to an anchor point not a part of the load) it is only providing a change of direction.

Was it just me or did his accent get stronger when working with the old guy.

This man could sell snatch blocks to a snatch block salesman

Yes pulleys are amazing but always remember the safe working limit of your cable / line / rope / strop etc quickly becomes the governing factor. Great production by the way, makes learning stuff fun !

"you cant push a rope"

well after a bottle of whiskey, im still gunna try

[ivanmacouzet]

Never seen someone so exited about physics as this guy.

Hey Destin, I bought some Snatch Blocks after this video came out (Same ones you used). Never used them but I got to today! We used a double snatch to lift up a heavy piece of furniture up some stairs. Only knew how to do it because of this video.

Hey Destin. I just used the "snatch block" technique with a come-along to get my tractor un-stuck from a pile of manure. THANK YOU for saving me from having to dig it out the poo! You really saved me.

You must respect the wires under tension. If they snap, they can kill.

[komolunanole]

I felt like I was watching a really long advertisement for a product called snatch block

[JACk]

I am so happy I was recommended this by YouTube. This guy was fun, I loved the interaction with his kids, and all the visuals and everything about the way he teaches! The snatch block was awesome and now I’m thinking how I can use something like this at my construction job!

[solarwind]

Jeremy is extremely smart and a great teacher. You are as well. Thanks for sharing your videos with the rest of us!

[scholarwhip]

I would have died if the sponsor was SnatchBlock.

[victorrosales]

This guy is the physics teacher we hoped for but never got.

[jennted]

Your enthusiasm for science and engineering is contagious! We've got snatch blocks on our wish lists now! We have also loved kiwi crates, my oldest spends hours building and playing with the awesome things they send her. Thank you for your video.
