“Cracking the egg sprinkler mystery”

There are some mysteries that occur only to the geeks in life. For instance, have you ever noticed that if you spin an egg in a puddle of milk, it turns into a milk sprinkler? Yeah, me either. Perhaps that’s because when most of us are baking or cooking, and we spill milk on the countertop, we just clean it up rather than playing in it.

Fortunately there are people out there who don’t clean it up, but spin eggs in it instead. And there are engineers who watch this and wonder why the egg sprays the milk outward.

Here, courtesy of NPR’s Science Friday, is the answer to this mystery…along with a pretty amazing discovery of a pump with no moving parts.

(Note: I love the egg proxy.)

    So, are you planning to start “Oregon Expat Science Friday” as a regular feature? :)
    I’m with you on spinning the egg in the puddle of milk, since it just makes a bigger mess of a smaller mess. Who thought of that??? Somebody’s mother wasn’t watching.

    Hmmmm, does the egg have to be hard boiled ? I think I might try it with a raw egg , then a hb egg. But this opens up more questions, does the size of the egg matter ? Or even how fresh it is. I’m lucky I keep hens so have an unlimited supply of test material lol.
