With so many cool things coming out each week, it can be hard to wade through all the rock-awesomeness. With ‘Cool Tools’, we’ve done the hard work for you.

This week we saw an entirely new way to play ping pong when your friends are busy, how to create an epic water balloon launcher for those upcoming summer neighborhood water battles, the world’s longest slackline walk and more…

Ready? Let’s go!

This week we look at:




“VOID Watches was originally launched in 2008 by Swedish designer David Ericsson. What started as a side project to a career in design and engineering turned into a full-time job and eventually a small company. Our watches not only tell time, they also tell the story of turning ideas into reality.”

Trainerbot: Smart Ping Pong Robot


“Trainerbot is the world’s first smart ping pong robot that can play with you anytime, anywhere. You can program specific shots, hone your skills and simulate games via an all-in-one app.”




“Spending time in nature helps you to reduce stress, increases your energy level and improves your mood. Wildfulness combines hand drawn nature scenes with psychoacoustic 3D sounds to create a world filled with nature – a world you can enter any time you like!”

Adobe Spark Page


“Spark Page makes it easy for anyone to turn words and images into a beautiful gliding web story.”


Water Balloon Launcher


“Here is how you can make your own water balloon launcher. We use high strength surgical tubing unlike many of the launchers you can buy online that don’t shoot very far. The cost of materials is about $18.”

Glass Bottle Cutter


“It’s interesting to know that you can make a glass from a bottle, engraving a cut all around the circumference and splitting it in two with a few tricks. If you plan to make many glasses and if you wish to obtain a perfect flat cut, you can preferably build your own cutting device.”


World Record Longest Slackline

“Slacklining is a sport with a lot of records, but trust us when we tell you this one is cool. On Tuesday, April 19 In Aiglun, France, the highliner and balance athlete Nathan Paulin, along with Danny Menšík, beat his own record for the longest highline walk in the world – over 1km.”


“Short film about the exploration on breathhold of the biggest wreck in Mediterranean sea, by 3 world champions Guillaume Néry, Morgan Bourc’His and Rémy Dubern. All the images were shot between 40 meters and 50 meters by Jérôme Espla (Poisson Lune Production) and his team with a RED EPIC.”

And there you have it!
