No childhood is complete without a few rounds of hopscotch now and then. Sure, it’s a little outdated to most kids today, but it’s still a well loved classic. For those of you that miss the days of hopping around on those little squares, you might like this new calculator. It shows the world that although you’re a responsible adult now, but you once were a child who was perfectly content with nothing more than hopscotch.

The numbers on the calculator are really nothing special, it’s how the calculator is laid out that makes it interesting. Part of the keys are lightly colored and the numbers themselves have a dark gray color. The darker keys make the calculator look like it has a miniature hopscotch game already going. Now instead of just punching in calculations, you can play hopscotch with your fingertips. Currently the design by Vadim Klbardin is in the search for manufacturers, so right now it’s not available.

This has got to be the coolest kit out there, make your own fully functioning roller coaster, I don’t know what father would not want one of these for upcoming fathers day (if my daughters reading this then please start saving)

It includes the classic roller coaster loop and for added realism the shoulder restraints automatically move up and down at the operating station. The included software lets you ride the coaster from any seat position and also provides true coaster geeks with a much needed real0time G-Force information.

You can build you own roller coaster for $159.99 from Think Geek. To get a better idea of how cool it is check out the video after the jump

Instead of taking a book with you to the beach, you can slip this case on your very own Kindle and read what you prefer right on your favorite gadget without having to worry about damaging it.

The polycarbonate case only weighs 6 ounces, which isn’t too shabby. The case is completely clear, so you’ll get to see all of your Kindle without too much getting in your way. The case is also pretty affordable for those of you on a tight budget. Right now it’s priced at $39.99, which is far less than it would cost to replace your Kindle after you manage to get it wet. Although keep in mind you shouldn’t dunk this under the water completely since it’s just splash proof instead of waterproof.

Image and video hosting by TinyPicI’ve always wanted one of the electronic weather stations, but for some reason I’ve never really gotten around to purchasing one. In part it’s due to the price and that I can hop on the internet and get a mostly accurate weather forecast. However, this tiny weather hub might be enough to get me to cave and purchase one. Especially since the hub can be hung on your fridge thanks to the handy little magnet.

It’s a pretty small fridge magnet, measuring 6.5 by 0.5 by 3.5 inches. It tells the indoor temperature in either Celsius or Fahrenheit, you can select your preference on the device. It also shows a 12 to 24 hour weather forecast with a graphical icon. Sure, it doesn’t show a ton of information, but for $1.49 it tells plenty of information. You can pick the Oregon Weather Hub up through Amazon.
