We all have those friends (or maybe even people who live with us) that love staining the table with glass marks. Now you can be honest in a funny way. Perhaps it is a little passive-aggressive but still in a polite manner. With these coasters, you will leave the message clear, and people will leave your table clean.
Simply pop this little wiener into water and watch it grow over the next few days up to six times it's size. When it loses all the water it'll shrink back to its original size meaning you can grow it over and over again. Great gift idea because it's bound to get a giggle.
