SinkScience #13 - Will It Spin??

[XxLeurxX]

Hrm... Not sure about what I'm asking about, but if you had the turbine running, and the pie pan static, wouldnt the pan warm up as a result of the magnets turning so fast? (Sort of like an induction oven)

[MrfixitRick]

@XxLeurxX

That is basically correct that the pan should heat up. However, the aluminum of the pie pan will dissipate the heat as fast as it can build up through magnetic induction.

(Provided the rpm's are kept relatively low, as shown. At high rpm's, maybe it could bake a pie! ;)

the fact that the first CD lifted - actually hovered - way cool. Paramagnetic properties of the aluminum coating.

[teddybearfer00]

I was thinking... when you placed the cd player, it spinned... but did it actually played the music??

[MrfixitRick]

No, it didn't play music. It's the world's simplest player motor, not simplest player.

lol nice vid

:)

WILL IT SPIN THAT IS THE QUESTION LOL XD

[unclewooly]

Good job guy's. Hanging out to see if atmospheric air venturied in at the source will increase turbine speed. Keep up the good work. It's good to see young minds thinking also.

[MrfixitRick]

Have a look at my latest 3 videos for mixing compressed air and water pressures at the same time!

Including one where the top blows off the turbine!

[GREENPOWERSCIENCE]

Try a hard drive platter. They should spin too even though a magnet wont stick to them. Cool junior scientist. Great video!

[adfhau]

Was just thinking the same thing myself - just pulled apart an old hard disk.. I mean, they're designed to spin up between 5,400 and 15,000 RPM... the trick I guess would be putting some sort of exit channel into the spindle or platters without shattering them..

[irkiIIer]

dude that can ruin the cd player

[MrfixitRick]

Hehe, I'll sacrifice anything in the name of science...or having fun!

[Daniel570C]

lol it doesnt matter xD theyre performing an experiment

[kurydebarcelona]

very imprecive!

nicely done Rowan!

[markuks]

wait a minute? Aluminum isn't magnetic? I have a suggestion on how to make the plate spin. Why not try cutting the edges of the plate and angle them so that you make something like a fan. I dunno might even fly...

[MrfixitRick]

Yep, did that and made a movie, but it didn't fly. Maybe on air pressure with more revs would do it.

The aluminum plate develops eddy currents that interact with the magnetic field of the turbine, producing torque on the plate.

ah youve an assistant i see,good to see science being passed on in a fun and educational way :)

ya know i was thinking,yes make a record player :D thatd be awesome haha,tho u might need to use an older disk cos the rooves were make too small in the end for i to be picked up by something like a regular needle,micro grooves? lol, now thats something i can tell ya about :D

[randomNstupid]

you mind if i re-edit your video? making it more short, adding alittle more color and the will it blend music?

[MrfixitRick]

Hey go for it!

[randomNstupid]

is Rowan your daughter?

[MrfixitRick]

Uh,no. He is my 12-year old student/assistant.
