If you’re looking to spend time in the water this summer and don’t have the wherewithal for scuba certification, you may want to opt for the Scorkl mini scuba tank instead. The name “Scorkl” is a mashup of scuba and snorkel, and the device itself is essentially a compact and lightweight scuba system, complete with a miniature air tank, an always-on regulator and a pressure gauge. It can be pumped by hand — using a special air pump that resembles a bike tire pump — and holds enough air for underwater dives up to 10 minutes. You can reserve your starter pack at Kickstarter for $200.
