I found something a while back and put it in the garage.
I found a decent sized box of all types of used corks. They were as follows:
678 wine corks
293 synthetic stoppers (made with plastic)
24 colorful corks (red, orange, etc.)
33 champagne corks
8 miscellaneous (odd size, strange handles on end, etc.)
1,036 total corks and stoppers found
Oh yeah, there was also a dime in the box.
Now, regarding the uses, there are LOTS of them. Cork can be used as a refrigerator magnet, chip clip, hot plate and even as a pencil eraser. Go to YouTube and you will find literally dozens more uses.
