We have a salad spinner.
Said salad spinner is something we got recently and is pretty cool really. However, I haven't used it a whole lot. It's not hard to use, you wash the lettuce, tear it up, put it in the bowl/basket combo, put the lid on, push down on the thing to spin it dry. It also has a brake which doesn't work right anymore because of an unfortunate dishwasher incident, but if you push really hard it will slow it down, or you wait until it stops spinning.
Except...I didn't. Without thinking through the consequences, I took the lid off while the inside basket was still spinning and guess what the consequences are? Let's just say I was picking lettuce off the floor and out of the toaster.
For future reference, either get the brake to work or wait until it stops spinning. Unless lettuce everywhere is a look you're going for. (Thankfully it wasn't all the lettuce...)
