Then I remembered that I saw this invention called the rimroller on an episode of Dragons' Den on CBC. It's essentially a keychain with a couple of blades inside that cuts a section of the coffee cup's rim and rolls it up for you. 'Sure beats doing it with your fingers, or your teeth for that matter.
I thought I'd go to Tim's today to test this gizmo out.
Let me tell you it's pretty cool. It doesn't increase you rrroll-up effieciency tremendously with 1 cup (what's another 10 seconds right?), though if you stood in front of a Tim's before work and did it for a dime per rim, you're sure to make your lunch money and then some.
There's a little problem with how narrow the cut is. As you can see from my test, there was only enough room for the French part. My sister also pointed out that you can't use it while there's still coffee in your cup. Apparently a lot of people are so eager to find out if they've won, that they start rolling the rim even if the cup's still half-full.
The verdict: If you happened to have the rimroller on you, it does make finding out if you've won a lot faster. And it's a really fun toy for you gadget geeks out there.
