London-based Bare Conductive makes paint that conducts electricity. It's called electric paint and it can be used on a variety of surfaces including paper, plastic, wood, cardboard, or glass.

Electric paint uses carbon to conduct electricity.

"Inside of this liquid, there are lots of small particles of carbon. When the liquid dries, those particles get closer together," Bare Conductive CEO and cofounder Matt Johnson told Business Insider. "When the liquid dries, those particles get closer together over which the electricity can flow."

Electric paint is used with a circuit board which can then be connected to a computer or a switch. The paint acts as a sensor for the device.

Since its launch in 2009, Bare Conductive has sold over 200,000 products and the paint has been at the core of several creative projects, like an interactive wall, a music play table, or a sound mural.

Following is the transcript of the video:

I’m going to show you guys some ab exercises that are very simple to do. You can do these very easily at home. Don't need any equipment.

What you want to do is you want to lay down. You want to put your hands underneath your glutes, okay? And you can do them with your head down, but I like to do them with a crunch up because it gives you a little more difficulty in the exercise.

All you are going to do is going to lift your feet up about 6 inches off the floor. You’re going to start your stopwatch, and you're going to start doing flutter kicks like this.

This is easy if you're a swimmer, I guess. But what you want to do, especially if you haven't ever done these before, is you want to start in, maybe 15 second increments. For me, I do 30 to 45 seconds at a time. So, these are called flutter kicks. Then what we're going to do is leg lifts.

You go right into it. There's no break. If you need a break, you can take a break, but I don't like to take a break. So, you’re still crunching up. You're doing little tiny leg lifts okay?

Then the next exercise are scissors. Just cross one leg over the other. Again, you're only about 6 inches off the ground. You don't want to go too high because then you're not engaging your abs. You want to keep your feet down about 6 inches off the ground.

So, now you're doing scissor kicks. Then we have the sways from side to side. This still works your lower abs but also gets a little bit of your obliques. And the other one I like to do is circles. You do one circle to the right and one circle over to the left, and just keep doing these.

Again, I do these in 30 second increments, but if you're just starting out, just try 15 seconds. And the last one are these circles where you put your feet in and then you circle out, and then circle in and then circle out. So, that's a great way to work your lower abs.

Being a woman and being 50 years old I really like to work the lower part of my obliques.

The next exercise I'm going to do is call the plank, and they’re very simple in the sense that again, you don't need exercise equipment.

All you are going to do is you’re going to get on your elbows and make sure your toes are facing the ground. You want your feet about hip width apart. And all you are going to do is make sure your hands are facing each other, just lift your body up.

You want to make sure that you have a nice flat position with just a little bit of lift in your pelvic area. If you’ve never done these before, start off with not a lot of time and then work your way up.

I do these for about 2 minutes. One way to make it a little challenging is to do rocking back and forth on your toes. Just make sure you always finish back where your shoulders are underneath your elbows, like that. Then you can also do little tucks. And just tuck, and maybe do 20 tucks, like that. And that’ll put more resistance on your abs.

Okay, one other thing I like to do… of course you see I'm not stopping, but you guys can take some breaks. I like to do hip rolls on the plank. So, all you're doing is rolling one hip and coming around and rolling the other hip.

You try to touch the ground. This will really really get you those six pack abs because you're working your obliques, alright? And the last exercise I like to do — it's still called a plank, it’s a side plank. Just lift yourself up.

Again, I'm going to put my leg over here because my right knee is bad. You want to make sure that you're not too far over or too far forward or you’ll fall down. And you can stay like this, which is a very difficult exercise, or if you really want to make it more of a challenge for your obliques, you do dips — Just so your hip just grazes the ground and then back up again.

So, just dip and up. You can do a number of them like maybe 10, or I like to do them for 45 seconds on each side maybe 3 times. And there are some ab exercises for you that are very easy to do at home.

This machine eats rubber. The ATR-300 is a tire recycling machine and it's sold by a Russian company. So how can a tire be recycled? The machine turns old tires into rubber "crumb." Rubber crumb is then added to artificial grass which softens the surface for athletes. It can also be used on playgrounds.

Here's how the machine works. The tires get cut into small segments. The segments are then ground up multiple times into smaller chips. Metallic material and the textile cord is removed along the way. The rubber finally gets cleaned and sorted. So the next time you play on fake grass, remember where that rubber crumb comes from.

No more annoying campfire smoke blowing in your face. This fire pit is smokeless. FirePit is made by BioLite and they are known for their wood burning camp stoves. How can a fire possibly be smokeless?

The smoke that makes your eyes burn in a typical campfire is caused by "particulate matter" escaping the fire. FirePit's 51 airjets inject the fire with oxygen using a rechargeable fan. This improves combustion by burning particulate matter before it has a chance to escape, which means a lot less smoke. You can control the intensity of the fire using the app. You can also use coals for cooking. The FirePit will cost $260.

This Czech brewery is using crayfish to monitor the water quality in their beer. The first water in their brewing process is pumped through the crayfish tanks. Each crayfish is attached to infrared sensors that monitor their hearts and cameras capture their every move.

When the pulse of three or more crayfish changes, it indicates that the water has changed. Computers analyze the data and tell the brewery if changes need to be made. The crayfish react quickly, so the brewery is able to see results within three minutes.

TreePod is a lightweight, portable alternative to the tree house you didn't have time to build as a child. The TreePod costs $325 and the company is planning for a new design. Now you can host the tree house party you always wanted.

The Tiny Cabin Architect, Ivan Ovchinnikov: "First of all I envision such house in remote areas — mountainous areas, on hiking or rafting tracks, which are impossible to access by car."

The cabin is only 172 square feet, but it fits sleeping areas, a kitchen, and a bathroom. It's solar panels power the cabin. A wood-burning stove adds additional heating. This tiny cabin has yet to hit the market. It cost over $34,000 to build, but the designers say future cabins will be cheaper to make.
