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 a new (free) writing app that deletes all of your words once the time goes off (!!), a candle that mimics a sunset, an exceptional update to the popular Waze GPS app, how to make a mini Da Vinci catapult and more…

Ready? Let’s go!

This week we look at:


Sunset Candle by Nendo


“t appears to be a normal white candle. But once lit, the centre of the candle begins to change colours as it burns: first to yellow, then orange, red, purple, and finally to blue. Not only does the candle provide illumination, but the transition of colours also serves as a reminder of the passage of time.”



“Inspired by the Japanese Shinto Kumi-ki puzzles, these wooden sculptures are a non-traditional take on the toy robot by joining ancient Japanese traditions with contemporary toy culture.”




“oneSafe is like Fort Knox in your pocket! oneSafe provides advanced security for your passwords with features like Touch ID, auto-lock, decoy safe, intrusion detection, self-destruct mode and double protection for your most sensitive data.”
