Today i wanted to make a kiwi/apple/strawberry/banana smoothie and added quite a bit of ice and when i was blending it, it just wouldn't go down so i had a plastic spoon and pushed the stuff down but the edge of the spoon got caught in the blade for maybe .5 of a second and a little chunk was taken off. (maybe the size of a pecan) I'm just wondering being i drank the smoothie. Will plastic do anything to you?
