We all love a good roadside attraction, especially those that are particularly compelling.

Some of these are commonly called mystery spots, places where gravity seems to work wrong.

Maybe it's an old shack built at crazy angles where everything flows the wrong way.

Or maybe it's just a stretch of road where cars will roll uphill.

Turns out there's some great science behind why these work.

And you guess what it is.

We're going to find out next Unskeptoid.

Hey everyone, Brian here.

A quick favor.

We're conducting an audience survey.

We'd be really grateful if you could take just a few minutes and answer our survey.

This is the kind of thing that's sort of an engineering and marketing necessity to make

the whole free podcast ecosystem flourish.

So please check it out.

So surveys are fun.

You get to talk about yourself.

Please visit survey.prx.org slash skeptoid to take the survey today.

That's survey.prx.org slash S.K.E.P.T.O.ID.

Thanks.

You're listening to Skeptoid.

I'm Brian Dunning from Skeptoid.com.
