Ever cooked pasta at home? Most people have, so you should be familiar with the situation where you’re getting the water up to temp and everything is pretty calm, until suddenly it blasts past the boiling point and the whole pot starts to shake and rattle in excited ebullition. It’s also dangerous if you’re standing around it when it happens, so we’re somewhat intrigued by the Ceramic Pot Minder from JBK Pottery. It’s small ceramic disc that works in two ways. One is by chattering at the bottom of the pot when temps start to get close to boiling, alerting you that you should come back and tend to your cooking. The other is by “modif[ying] the size and number of bubbles rising to the top of the pot, preventing messy boil overs.” It’s made from fully vitrified porcelain ceramic, and should be able to be used over and over again. $4!
