Of all the ways you can show off your bravery this summer—parasailing, whitewater rafting, shoving 37 hot dogs down your gullet a la Joey Chestnut—this stunt might take the cake: The Alamo Drafthouse in Austin Texas, which pioneered serving beers during films and thwarting would-be movie texters, is showing the classic 1975 blockbuster Jaws from June 30 to July 23. There’s just one catch: You’ll have to watch it while sitting in an inner tube on a lake at night.

This, of course, is a pretty gnarly thing to do if you’ve ever seen Jaws or have any familiarity with Steven Spielberg’s first masterpiece. The flick is about a great white shark that terrorizes a New England town and menacingly lurks in the ocean, waiting to sink its teeth into unsuspecting swimmers.

So sure—why wouldn’t you head to Volente Beach Water Park on Lake Travis (45 minutes from Austin) and float in open water while a devil fish monster wreaks havoc on the big screen? I’m not saying that Alamo Drafthouse has stocked Lake Travis with vicious sharks explicitly for this purpose … but I’m also not not saying it.

Admission is $55—a sufficient price to pay to get the bejeezus scared out of you—which also includes refreshments, brews, and access to water slides before the movie. Look, it’s your call, but this is basically akin to watching the movie Flight on a flight.
