This is a great trick to know if urine trouble.
If clear liquids can be conformed to the shape of a sphere, sunlight can be refracted through the fluid and the energy can be focused to a point.
Clear water is one of the best choices because it doesn't absorb any of the suns energy, so more heat is transferred to the tinder. Colored liquids, or liquids in colored bottles can still work, but energy is lost, and that could be the difference between getting tinder ignition or not.
After making fires with various water bottles, and posting my first video on it in 2010, someone commented and said they saw a guy on Dual Survival do it with his urine. That sounded pretty amazing to me, so I looked up the link on YouTube and saw the clip.
It seemed like he had quite a bit of trouble actually getting his fire going, and I thought that if I were ever in a survival situation like that, the last thing I would want to be doing is trying for hours how to figure out how it works. It's better to be prepared beforehand.
This video comes after many experiments of playing with various techniques. I found that using plastic wrap and urine made a combination that gave great success, and within a minute or two I could have a flame! When done correctly, it works just the same as a magnifying glass.
Practicing with the amount of pressure is key, because too little and you won't have a good lens. Too much, and the plastic bursts and you're soaking wet.
Q: Why did I wrap an apple in plastic wrap?
A: Of course the video is fictional, however the survival techniques portrayed are real. I wrapped my apple with plastic wrap because I've seen it done before at hotels, and I wanted to give an example of how random resources can be used as tools. If you don't wrap your apples in plastic wrap, perhaps you wrap your sandwich, or various other food items? The plastic baggie holding the celery can also be used in a very similar manner.
Q: Why did I use a page from the map for tinder instead of grass or leaves?
A: This liquid lens technique will light any tinder that could be lit with a magnifying glass, since that's what it is in essence. I used a piece of paper as an example because most people have access to that as a material they could practice with. I chose paper because it's easily duplicatable by anyone wanting to try.
Q: Why does the urine change color just before I light the tinder? Did I cheat?
A: The urine changes color mid video, and that's because when I went to re-set my camera for a different angled shot, I dropped the first sack of urine. Awkward to hold the sack, and adjust the camera on rocky terrain at the same time. I lost my urine and had to wait for another round .. which, by that point was more hydrated because of all the water I'd drank earlier, and therefore more clear in color. In either case, I have the same success igniting tinder with either liquid lens so the difference made by the color is negligible.
