You need a stronger magnet at the front obviously.

Or it’s a toy American truck and they’re metric magnets. Swap them for federal units.

Water destroys magnets. Thank you for your attention to this important matter.

Well duh. Why else would the magnetic record on the sea floor flip back and forth?

So you can hear the 'B' side.

We used to make these all the time as kids. You need a second pair of magnets in push configuration on the back for this to work.

Don't forget the spark plug wrapped in wire that's been taped to a light bulb

With the right electric field you can generate (a small amount of) thrust our of ions in air flowing over a charged plane.

One of the myth-busters "anti-gravity" devices they tested was actually (very weak) a static electric ion thruster.

Pretty cool - but it did need electric power input.

What about the 4 magnets on the sides for turning!?

[–] Eh_I@lemmy.world 0 points 3 days ago

You're going to need a three-way monopole electromagnet if you ever want to reverse.

You have too pee on the truck bed

You gotta release the parking brake

Just gotta pull yourself up by your bootstraps and figure out out like i did.

missing microwave transformer, HHO electrolysis, cellulose, and nitric acid bro... obviously

The magnet dislikes you personally, that's why.

Far too many people think this is how “energy” and “frequencies” work.

[–] knacht1@lemmy.world 0 points 3 days ago

It used to work till you broke it.

[–] ShaggySnacks@lemmy.myserv.one 0 points 3 days ago

Fucking magnets, how do they work?

You're pointing to my colleague?

[–] SapphironZA@sh.itjust.works 0 points 3 days ago

The handbrake is still on.

[–] nexguy@lemmy.world 0 points 3 days ago

I think it is working. Exactly as designed.

[–] apotheotic@beehaw.org 0 points 3 days ago

Rookie mistake, the thing holding the magnet from the back side is also metal so it cancels out
