Ice Ball Maker & Sphere Ice Mold by Bar Brat.

These make awesome ice balls for drinks they do not melt fast and will last for several drinks. I love how the ice balls look in a drink if you are having a small get together it had a unique design to drinks.You can make 4 small ice balls in each tray. The first think you want to make sure is that they are closed all the way so you dont make a mess. Then you pour the water into the small hole in the ice tray. Then you freeze for several hours and they are ready to go. Its so simple to use. When you are ready to use your ice balls you just simple pop them out. The tray is made out of silicone so you wont have trouble removing them. I love how easy they are to bend around and they dont break. If you want to be a little wild you could put juice in it or make jello shots in these trays for a fun surprises. I highly recommend them.
