A Slurpee trick

A. Note the Dome on the Mountain Dew Slurpee.

This is a handy trick for easy Slurpee drinking after you've gotten down to about half way through a large sized cup. Eventually the slush level gets low enough that your straw lacks buoyancy/support enough to stick out of the dome. Or at least it doesn't stick out of the dome enough for convenient access.

Rather than removing the lid or engaging in an unnecessary amount of "lip grasping", take the dome and push it down into the cup so that the convexity pops into a concave shape. Voila. You have easy access to the perfectly centered straw, but still have your convenient covering for your remaining drink.

B. Note the "Timulated" dome on this Slurpee.
Mighty convenient, eh?
(Is that a pie on the stove? How old is this photo?)

And your straw is still kept conveniently centered.
