The Shepard-Risset Glissando
A Shepard tone, named after Roger Shepard, is a sound consisting of a superposition of sine waves separated by octaves. When played with the base pitch of the tone moving upward or downward, it is referred to as the Shepard scale. This creates the auditory illusion of a tone that continually ascends or descends in pitch, yet which ultimately seems to get no higher or lower. It has been described as a “sonic barber’s pole”.
Jean-Claude Risset subsequently created a version of the scale where the tones glide continuously, and it is appropriately called the continuous Risset scale or Shepard–Risset glissando. When done correctly, the tone appears to rise (or descend) continuously in pitch, yet return to its starting note. Basically, it’s a continuously descending tone that never gets any lower. It’s the acoustical version of M.C. Escher’s Penrose Stairs optical illusion. Source.
Doesn’t it sound a little bit creepy?

This has been disproving the government’s bullshit with Lily
1) Does not hurt rhinos
2) Discolours ivory (BRIGHT PINK) thus reducing saleability
3) Can be detected by airport scanners, even if ground up, thus increasing the chances you will be caught
4) Causes nausea, vomiting, and diarrhea if ingested by humans, thus driving away your customer base
Win. Win. Win. Win.
Lake Maracaibo in Venezuela gets struck by lightning more than 200 times every year – that’s more than anywhere else on earth. Source
Fve-miles above Lake Maracaibo, storm clouds gather up to 160 nights per year and can last for up to 10 hours.
Your body is an incredibly bizarre machine.

According to research from Charles Paxton, fisheries ecologist and statistician at Scotland’s University of St. Andrews, published in the Journal of Zoology this month, the giant squid could grow to reach as much as 65 feet. But even that is a “conservative analysis,” as size could protect against their #1 predator.
