Have 500 sodas or return them from the McDonalds that you stole them from.
Those are black...mikkeys are white with yellow stripe... black are usually from higher end restaurants or food supply chains.

Make a flow straightener for your wind tunnel
Make five hundred straw clarinets? Super fun little things that take 500 straws to truly master... I read about them somewhere online... They're awesome. :) I'm always lacking in the straw department, so you could also send a couple hundred to me... maybe... ;)
Make a really big Bell tetrahedron kite.
Find 500 youngsters and create your very own spitwad army.
Sell some, and with the money, buy black powder, then fill a bunch of 'em up and you just got a tone of fireworks !
Great idea and link.
Push them together to make one REALLY LONG straw. Or try and sell them, who knows, you might get lucky.
A lamp.A chair. A lamp. A Sierpinski tetrahedron. Tensegrity structures. Several dozen other things. (Mostly lamps)A Bridge.A bunch more things. Or drink through a straw for the next 500 drinks. It's not like they'll spoil!
