Thanks to its microscopic budget and major success at the box office, the 2007 film Paranormal Activity, scored a return on investment of 19,758 percent, absolutely blowing away the next most profitable film (2015 horror film Gallows, with an ROI of 6,843 percent).

You might not be able to identify a current Swedish musician or band off the top of your head. However, there is no question that you have heard Swedish music.

Since winning the Eurovision Song Contest in 1974, this band has opened the way for other Swedish talents. This includes musicians such as Roxette, Robyn, Lykke Li, Avicii, and others who have achieved international acclaim. If you like ABBA, you should go to the ABBA Museum in Stockholm.

Other minerals can be combined with sand, lime, and soda ash to produce different colored glass. Adding nickel oxide, for example, results in the violet glass.

When Perseus took Medusa’s head, we are told that something extraordinary happened. When Medusa was raped by Poseidon, it seems that she got pregnant but for some reason, never gave birth. Consequently, when her head was removed, two children sprang from the opening. These were Chrysaor and Pegasus. Chrysaor became the father of the three-headed (or three-bodied) giant Geryon who is mainly known for his fight with Hercules. Pegasus was a winged horse and one of the most famous mythological beings. So why did Gorgon Medusa give birth to a horse? This must have to do with the fact that Poseidon was, amongst others, the god of horses.

He did at first, but it didn't last long. After 1928, Walt stopped animating in favour of concentrating on the direction and development of stories.

He never included Mickey in any of his theatrical releases.

Beetroots are a type of root vegetable that is distinguished by their rich, dark red color. This color is caused by the presence of betalain, a red pigment that is responsible for the vegetable's bright coloring. This same pigment, however, might cause your feces to become black after ingesting beetroots. This is due to the fact that betalain does not break down in the digestive system and instead travels through the body and is expelled in the stool.
