My Homemade Jetpack Should Be Illegal

In my opinion, Adding more thrusters in a straight line quickly hits the wall of diminishing returns.
Instead, try mounting and stacking them in a cylinder and surrounding the collective ends in one large cone nozzle. This is how rockets are designed, with many burners in a ring inside of the larger cone that funnels the final air mixture in around them all.
If you place them closer together in a ring and encapsulate them with a blast cone it should direct the collective force more efficiently.

As an aerodynamicist I have one word for you - Streamlining! The mask, the, tank, the backpack - you'll break 20 mph for sure and that would be even more amazing. Great Show!

the true kerbal approach to problem solving, add more engines until you get the results you desire

I love everything about this, but your random songs especially make me smile ear to ear man 😅

This dude is single-handedly keeping the water jetpack company in business.

Maybe a swimming cap and smaller goggles could lessen water resistance. Also placing some shrouds near the propeler intake to prevent seaweed or debris from cluttering it in every use. Hoping to see you break records with your cool ideas. More power :)

I swear Preston’s always in a good mood 😂 literally one of the most underrated YouTuber!

looks like you're ready to take on the final boss. let me know when u want to come out and race

Instead of doubling it, Multiply it by Pi! Make an aerodynamic (or hydrodynamic?) circle frame around you that you can hold on to.

This video is next level awesome in every way from the videography and soon to be #1 iTunes hit about Jam Nutsto the overal humor and entertaining interactions. It was a great idea that paid off with a cool finish. Great stuff!

FBI: We heard you made your own underwater jetpack, we need to talk about your known associates. .

Only 12? Double it and make a second row behind it

[Jenisonc]

Also Sprach Zarathustra was a great addition to your super gear moment. Truly goosebump worthy.

No joke: Preston never gives us up, never lets us down, never runs around or deserts us. Never makes us cry, never says goodbye, never tells a lie, or hurt us.


Edit: But for real, Preston makes the best content on YouTube for sure. I’ve never laughed this hard at something before. Seriously. Also the Mrbeast and Ryan Trahan songs are still stuck in my head lol.

Saw this at the top of my side bar and immediately clicked off the other video I was watching. So many great choices here. Like the scene in the water where we couldn’t actually see you but it was still captivating due to the music choice. Also that final “Double It” in the song is so clutch! If it’s true that we get better with time, I can’t imagine the heights you sill reach. Bravo!!!

"The ballon dipper thing that kept happening" got me man 😂

Seeing the aerial view looks like when David Hasselhoff saved SpongeBob

You should see if Robert can get you guys into an Olympic Sized Pool to really push the jetpack and maybe move the two outer motors to the middle on a raised section or pair them into 4 sets of triangles to try to reduce the jets from interfering with each other
