Three more volcanoes—Mount Kerinci in West Sumatra, Mount Semeru in East Java and Mount Merapi in Central Java—showed elevated activity on Friday, on the same day that Anak Krakatau erupted.

Rebreather diving has gained popularity over the last few years. As you can imagine, these high tech dive units are not cheap. As with any large investment, buying your first rebreather can be daunting. Before you make the big purchase, it’s crucial that you dive and test out a variety of different models. But where do you start? How do you know what’s the best rebreather for your style of diving?

Though rebreathers all perform the same task: removing additional CO₂ from the breathing loop while adding the necessary amount of oxygen or nitrox – The way different models execute this task varies. Remember, a rebreather is a huge investment, and thus it’s important that you take the time to find the right machine for you and your type of diving.

One of our goals here at The Adventure Junkies is to make your life easier when it comes to gear shopping. In this guide, we’ll walk you through some things to consider before buying a rebreather and show you our selection of some of the best models out there.

Scientists have known for centuries that light is composed of waves, but the fact that light can also act like a liquid, that is rippling and spiralling around obstacles like the current of a river, is a much more recent discovery that is increasingly an area of extensive research. However, as you’d expect the “liquid” properties of light only emerge under special conditions when the photons that make up the light waves are able to interact with one another.

When a Tesla meets the “Back To The Future” franchise, we normally end up with a match made in heaven. The Palo Alto carmaker has even released an Easter Egg revolving around this connection last year and we are now here to talk about a rendering that takes the link to a whole new level.
