Well, yeah, magnets don't repel against anything except magnets.

Unless there's some physics-shattering discovery some day, there will never be something compact that just repels against the surface of random ground. And no matter how much power you have, it definitely won't be able to repel against water.

At most, perhaps some day after our grandkids are dead there could be super powerful little jets that can force enough air downward in a tiny space to support the weight of a person, but human extinction will probably occur first, and static levitation is impossible.

(They use gigantic machines to generate a magnetic force to levitate a tiny frog, but that kind of force will never be compact nor support any meaningful mass.)

Also, the first dog being a Jack Russell Terrorist made it look too easy.

Mine had a 4' standing high jump. Made it look like levitation. Every landing on the table was like a boss.

Pull my finger! Scientists solve knuckle-cracking riddle

jubuttib says...

Not quite, he (Donald L. Unger) won an Ig Nobel prize, a satirical version of the Nobel prize, given to "honor achievements that first make people laugh, and then make them think". Basically anything that sounds way too silly but can still yield useful knowledge.

While silly, it's still (usually) all based on proper scientific method, and there's even an example of a man who first won the Ig Nobel prize in physics in 2000 (for levitating a frog with magnets), and then later went to win the Nobel prize in physics together with Konstantin Novoselov for their work on graphene. =)

I believe someone won a Nobel prize for spending several decades of his life cracking the knuckles of one hand and just that one hand every day to see if there are really any negative effects from knuckle-cracking.

In his case there weren't.
