This usually occurs shortly after you've filled it full of ice and water.
This is also handy when you have a baby who grabs and bats at anything and everything near him and manages to spill your water for you on the rare day that you don't do it yourself.
It's also plastic, so it won't break and shatter glass all over your floor for your baby to crawl in, or for you to step on which would cause a bloody mess.
One great feature about this is that it's double lined, meaning it won't sweat all over your coffee table or dining table. No one likes wet rings on their furniture.
The one question I have is why didn't I just get one of these a long time ago? It sure would have saved me a lot of cleanup.
