If you could fill a swimming pool with anything but water...

[SwimmingRock]

I would fill it with lettuce, lesser soul gems, and yarn.

I see what you did there.

I was about to ask what he was going on about. Thanks for the explanation.

Corn starch+water mixture. Then I could run across it.

You totally should. It's so much fun.

OT: an orgy Innocent, wholesome fun things for the whole family
Honestly, I'd probably just set up an awesome videogame system. Think of the surround sound echo.

 

[Queen Michael]

Either Pocky or Reese's Peanut Buttercups.

Scrooge Mc duck in it.
GOLD COINS!!!

Use the money to buy a real pool.

 

[ZeZZZZevy]

ACCOUNT HAS BEEN ABANDONED

 

[Ace of Spades]

I'd fill it with money and swim around in it like Scrooge McDuck.

 

[DefunctTheory]

Hot, naked women.

Standing straight up, of course. No need to suffocate them.

And who says they have to STAY in the pool?

 

[Jonluw]

That slimy shit that Mythbusters filled it with.

Or perhaps corn-starch.

 

[RedMagic]

Rootbeer, then I'd dump a truckload of ice cream to make the largest outdoor rootbeer float in the world.

 

[liveslowdiefast]

Angel delight. FTW

 

[Harry Mason]

Naked Goth chicks and fake blood.
*sigh*

 

[Sticky Squid]

Ham for no particular reason.

 

[StellarViking]

Scotch and those cool little stone squares you put in the freezer that keep your drink cold without getting it watery.

 

[icame]

Cofee, hot chocolate and whiskey mix. It's actually pretty bad ass.

 

[Srrrh]

Hot, naked women.

I would add chocolate to this so I can shout "DIP ME IN CHOCOLATE AND THROW ME TO THE LESBIANS" and then someone can actually do this.

Fill it with money.
Use the money to buy a real pool.

Damn ye, ninja pony.

...I suppose I could make it more specific, though. I'd fill it with $50 bills. I don't think I've ever heard of those being counterfeited.
