Today I did a very stupid thing!

try to make smoothie drinks for kids party. Put fruits and veg. into the blend (expensive blend). Then press the button. Guess what, I accidently put a stainless spool there. I wear the ear plug everytime when I use the blend. I did feel something stuck there, but thought it was caused by some hard fruits (apple, I didn't cut into small pieces). So I didn't stop it right away after I felt something wrong. Then after my smoothie was done, I have found a bended spoon inside of the blend. I wish it would not damage the blend since I use it quite often. What a stupid thing I have done.
