I’ve had a cheap (was $15) single salad spinner, for about 15 years. Decent amount of usage in that time, but not professional level.

So my question to you is: what the heck are you doing to your salad spinners?

If you spin low-grade uranium ore just right, the heavier particles will deposit on the edges, giving you high-grade uranium.

Please follow HN rules that forbid nuclear proliferation.
