Five Clam Reward!

I have a smoothie cup (it's insulated so my smoothie stays cold) that came with a reusable straw. I've been making blueberry smoothies recently since the little delights are in season. Unfortunately, the straw gets these little bits of blueberry skin stuck in it. I realize I should rinse the straw immediately after finishing the smoothie, but let's just assume for the benefit of this post, that it's not a possibility.

SO. I have $5 for whomever can come up with an effective cleaning method for the straw that a) doesn't involve soaking and b) doesn't involve my dishwasher. Help is appreciated!
