If you have a bit of an imagination, the Hydroglass shower is almost like snorkeling off of some pristine Caribbean island. Alllllmost. [Hydroco via Link]

Again, if you have some imagination, the Aquavolo can be like standing in a refreshing rainstorm on a hot summer day. It can also be like standing in a stream underneath a waterfall with a simple flip of the showerhead. [Bossini via Link]

It may cost $1000, but this portable spa is still cheaper than most hot tubs and it can be drained and deflated quickly for storage. It also features five adjustable hydro-massaging jets and a 900W heating system that can be controlled with the push of a button. [Hammacher]

The Mr. T sprinkler I had as a kid did the job, but it is nothing compared to what I could have done with this remote controlled water cannon. It attaches to a standard garden hose and can shoot water up to 100 feet. And the best part is that it can be controlled wirelessly via remote control. It also includes three interchangeable nozzles to alter spray patterns. [Hammacher]

Slip 'n Slides are a classic alternative to the backyard pool, but with a little work you can easily put one together yourself. Check out the following link to see this extreme homemade version in action. [Link]

You may not be able to get to the beach this year, but you can still simulate an underwater experience with the Umine projector. In addition to projecting sea-like waves, the Umine features sound effects that help immerse you in an ocean experience. [Himeya via Link]

If you are looking to save a little money on your water bill, a rain barrel is a smart way to power up your sprinklers and fill your water weapons. This particular 56-gallon rain barrel happens to be butt-shaped, which will no doubt open up a world of opportunity for hilarious diarrhea jokes. [Link]

The next best thing to a pool with a diving board is a water-logged Big Wave trampoline. Water, trampoline...what could go wrong? [Big Wave]

There are commercial water mortar toys, but they won't hold a candle in terms of firepower compared to one that you build yourself. This DIY version is easy to build, and it's a serious piece of water fightin' artillery. [Instructables via Link]

Plus, the wind doesn't require huge expensive D batteries, of which this inflatable cash sink requires eight.

The wind also dissipates eventually, takes up no room in your garage, and won't pop or become mangled when your kid—innocent and adorable, yes, but naive as fuck—tries to use this thing on the lawn when he gets bored in the pool.

Still not convinced? The 360 degree movement, all at a neck-breaking 2MPH, is too much to pass up? OK, then, purchase away. Just be sure to send us a picture of the thing in six months when it's stuffed in a closet next to your Snuggie collection. [Cooolest Gadgets]

Indeed, the Aqua Sounder will not only transmit your MP3 player tunes from a dock positioned up to 150 feet away, it will also provide ambiance with two LED mood lights. It's completely submersible, and you just might be tempted to use it for a game of pool dodgeball, but I would have to caution against it. [Grace via I4U via DVICE]

The X-wing (pictured here) is not only 5-feet long; it includes a water cannon. Couple that aqua weaponry with a few "pew pew" noises and you've got yourself a second degree sunburn before anyone even pulls out the Death Star beach ball.

Seriously, I'm calling a do-over to my childhood. But I can wait until Power Wheels releases a line of working mini Tie Fighters. [StarWars via OhGizmo!]

This Aquavee portable swim system offers similar benefits, allowing you to "swim in any style at any time" and continue swimming as long as you're able to keep flopping and kicking. It works by using a harness and suction cups to hold you in place. Suction cups are, as you know, the world's most secure way to attach something, so you know this is going to work forever. On the bright side, you won't have to plant stakes into the ground—something that's not quite kosher if you live in an apartment complex like us. [Aquavee]

Enter the ExerSwim. This is a device that can be rolled into the pool and will create a constant current that is great for swimming against. Think of it like an underwater treadmill. Although, you may be better off buying enough land and installing an Olympic-size swimming pool, because the ExerSwim carries a hefty $4,000 price tag. –Travis Hudson

You can't really install these things in public pools, however, since it requires you digging holes and mounting a pole into the dirt. But for $70, your own home can become a much better place to train for the triathlon. For the biathlon you're going to have to build yourself a mountain and a shooting range. – Jason Chen

The Verro 300 ($799) is best for harder surfaces (like concrete) while the Verro 600 ($1,199) is intended for tile or vinyl. Not a bad way to clean your pool. – Louis Ramirez

Newsflash. They. Still. Are. While you were settling down, growing mentally and physically soft, accepting the practicality of the three-piece suit and generally bending over to take one from society, sharks didn't go anywhere. They were still kickin' ass—shark style.

Get back in the game, twinkies. Because a hammerhead+water cannon will equal you getting your balls back. Just see if that dry cleaner still lost your favorite shirt when they tell the story to a freaking hammerhead that's housing freaking water artillery.

Commence. – Mark Wilson
