If you apply sunblock to yourself, you may miss spots. And it can be awkward to ask someone else to rub it onto your hard-to-reach areas. That's why this invention could be handy. It's called the SnappyScreen. It sprays sunblock over your entire body.
First, select the SPF level that you want. Then tell the machine whether you're under or over 5 feet tall. It gives you several seconds to step inside. Then it sprays a sunblock mist on one side, gives you time to turn around, then sprays the other side.
The SnappyScreen is currently available at 10 resorts in the US and Caribbean. But the developers hope to eventually make it available at waterparks and ordinary swimming pools.
