Kids and stuff getting spilled are two things that go together in life. SipSmart lets parents and caretakers put a spill-proof lid on bottled water, juices and smoothies. The mess prevention technology works because of the anti-leak, choke prevention valve near the top of the straw and the stopper below the screw cap. The beverage’s original cap just gets discarded and replaced with the SipSmart bottle cap for liquid security and a small addition to parental sanity. While it’s probably safe to assume that the caps can be reused, it’s not clear as to whether or not they are dishwasher safe. For $20, backers get two sets and an expected delivery of January 2015.
