Because of the weight of the ends of the forks, and how they’re distributed behind the penny (closer to the glass), the center of gravity of the whole system is actually shifted quite significantly. If I’m right, it would actually have to be right where the penny meets the glass. This mean, in a sense, all the “weight” of the system of the forks and penny is resting right on that point, rather than out in the air, so if you balance it, it’ll be stable on the glass.
Jellyfish Lake in Palau. Apparently the jellies have lost their ability to sting because of lack of predators in the lake and you can swim with them!
WAIT BUT THAT’S NOT EVEN THE COOLEST PART: These jellyfish carry small populations of algae inside their bodies and derive much of their nutrition from the sugars that the algae produce. The jellyfish follow the sun across the lake each day and rotate continuously, so that the algae are always getting maximum sunlight exposure for photosynthesis. Then at night they dive to deeper parts of the lake so the algae can absorb nitrogen. It’s one of the best examples of endosymbiosis in action and it’s KICKASS.
“I want to get married, though, I want children - to me that’s the ultimate thing. When you’re old and on your death bed, looking back at your life it’s not going to be the films you’ve made or what you’ve accomplished, it’s the relationships you have. You’re survived by things that matter - the people you love and those who love you back" - Chris Evans
