Hey I’m just saying, the reason that using a narrowing tube to increase air velocity didn’t really work is because, it’s only feasible when you have pressure to spend. Axial fans like these really produce barely any pressure at all, so the most you are doing is choking it when you built it like that. Cool build though!
Hi thanks for the comment! Completely agree! The turbulence generated from the side walls and narrowing diameter definitely needed more initial pressure - which is why the open ended version worked so much better!
Sort of. It does two things. 1) it does increase air speed (which also means that as it leaves the nozzle, it pulls along some more air from around the nozzle), but 2) it also directs it closer to the leaves. By using a nozzle, the fan and motor and such can be at your hand for easy mobility, while still directing the air right above the leaves. It's the difference between holding a chainsaw by the handle or at the end of a pole. The nozzle allows the air to blow directly above the leaves without putting the fan itself directly above the leaves. In this, the fan is right up against the leaves, so that second part doesn't matter. His nozzle was effectively useless. The first part (what you mentioned) still applies, but surface resistance turned it from a benefit to a drawback.
LEGO Leaf Blower aka the LEGO rabbit slicer!🤭 That's impressive blowing power, man! Did you test it without the liftarms mounted to the track pieces? Would it just slip or why the effort?
I tried 4 blades - too much torque required to move 4 blades worth of air compared to 2 and hence resulting decreased rpm and overall less wind speed. Thanks for watching!
Thanks for the comment! Each of those clicks is an actual recorded clicking together of LEGO pieces. They aren’t fake. They are recorded by myself. Thanks for watching!
Leaf blower - what next? the kitchen sink! Brilliant your designs are amazing.
Ah, thanks for the kind words! I've got a few ideas up my sleeve...
NO WAY
can bro see into the future

Wife: can you clean up those leaves?
Husband: *3 months later*
I love how this guy has hundreds of those grey frame pieces and I have like 2 lol
I LOVE this type of videos man, and bro u could make like a leaf cutter or, idk man but for sure im subscribing to you!! 🔥
They use something like this to clear ice and snow from train tracks too, but with a jet engine!
at 1:30 a beat drop hits
So cool!
Thanks! I appreciate it!
Cool build
Cheers!
wow Supper LEGO. Great 😍
YAY! YOU'RE BACK!
Now your yard will be clean :)
Thats awesome! It looked really cool.
Thanks! Glad you enjoyed the video!
Dude has an ambition
Very good lego video
I wonder what takes longer the Building process or the stop motion editing.
Sometimes idea generation takes the longest!!
This video doesn't even have a thousand likes. That is criminally underrated. These videos are awesome and deserve much more attention
Ah I appreciate the support! Thanks!
Put it on train wheels and see how well it works as a propeller!
It must take a while to plan these builds but cool build 😊
Thanks! Underrated comment! Ideas and planning is pretty much the hardest aspect of these videos!!
Is it an idea to use venturi to have more air out the nozzle?
Sort of. It does two things. 1) it does increase air speed (which also means that as it leaves the nozzle, it pulls along some more air from around the nozzle), but 2) it also directs it closer to the leaves.

Yeah a lot of slip - especially on the heavier blower unit. Plus it looked better proportioned!
Build a working street sweeper
woww ideas
Can you build a Inversion 360° toy of Play City with lego? It would be awesome
Could you try building a car that goes on a circular rail and try to get a huge top speed
I’ll add it to the ideas list !
Where do you get those fan blades from? I have been searching but never found them...
Great question! They are from the LEGO 9688 Renewable Energy Set!
Bro where u buy this Legos?
‘Bricklink’ mainly! Thanks for watching!
how i can't see his hand in the video ?
Its moving so fast you just can't see it!
(It's actually stop animation) Thanks for watching!
It would be better with 4 blades instead of 2

now make a full size V8
:o
Крууууууто
plz pinme
The fake building noises can be kinda annoying, could you just use the real building noises?

Your alone on this one
