- 8. 4*. Emma Stone’d Originally intended as a cough drop which would be effective and safe for child consumption, this cough syrup was patented by Bayer A.G. This was marketed as a non-addictive replacement for morphine but, lo and behold – it turned out to be addictive and quite dangerous. This drug has been the fancy of many movies and even today remains a fairly popular item. Name the drug.
- 9. Heroin
- 10. 5. Are we more than the sum of our parts? Tool is one of heavy metal's most eclectic and original bands, and their best songs reflect their musical ingenuity.

- 15. 7. KarDashian People are very secretive about this recipe. The basic idea is to take a solid and convert it into a HUUGE amount of gas to fill a common safety device. An old recipe was to take a container filled with NaN3 and add spoons of KNO3 and SiO2 to it. This recipe was inherited from military and rocket propellants industry. Heat the mixture using a 12V battery. A very heated chemical reaction will start releasing N2. This will make your safety device ready in less than 1/25th of a second. Name the safety device.
- 16. Airbags
- 17. 8. Cherry, Blueberry, Pecan & Shepherd’s
- 19. 9. You will never guess this! DHMO is perhaps the single most prevalent of all chemicals that can be dangerous to human life: DHMO: ■ is also known as hydric acid, and is the major component of acid rain. ■ contributes to the Greenhouse Effect. ■ contributes to the erosion of our natural landscape ■ accelerates corrosion and rusting of many metals ■ It is used in certain torture techniques ■ has been found in excised tumours of terminal cancer patients. ■ Used as an industrial solvent and coolant. ■ Found in nuclear power plants. ■ Is a fire retardant. ■ Used in the distribution of pesticides. Even after washing, produce remains contaminated by this chemical. ■ as an additive in certain junk foods and other food products. What is this dangerous chemical we are talking about?
- 20. Dihydrogen Monoxide - WATER
- 21. 10. Enigmatic X was prosecuted in 1952 for homosexual acts, when "gross indecency" was still criminal in the UK. He accepted chemical castration treatment, as an alternative to prison. X died in 1954, 16 days before his 42nd birthday, from cyanide poisoning. An inquest determined his death as suicide. In 2009, following an Internet campaign, British Prime Minister Gordon Brown made an official public apology on behalf of the British government for "the appalling way he was treated". Queen Elizabeth II granted him a posthumous pardon in 2013. The X law is now an informal term for a 2017 law in the United Kingdom that pardons men cautioned or convicted under historical legislation that outlawed homosexual acts. Who is X?
- 22. Alan Turing
- 23. 11. This is very in-fashion The following pictures depict changes in some dog breeds over the last couple of centuries. Aside from the obvious visual differences, the emergence of health defects has been found - particularly in dogs from purebred lineages. This is because of a certain way of breeding, which has also been used in cows and plants to generate offspring of certain desired characteristics. What is this type of breeding called?
- 25. Inbreeding
- 26. 12. Twice as nice We all love pies. But do we love the mathematical π (Pi)? There now exists a faction that wants π to be removed as a mathematical symbol, replacing it with another symbol τ (Tau), that is supposedly more intuitive than π is. In fact, like π day is celebrated on March 14th, the followers of Tau also celebrate τ day. When is τ day celebrated?
- 27. June 28th
- 28. 13. Don’t play with _____ When John Walker used a stick to stir a pot containing a chemical mixture, part of the mixture stuck to the end of the stick. This combination had a useful property which resulted in the invention of X. In the later versions of X, Sb2S5 had been replaced by Y. The modern variants are safer because white Y has been replaced by red Y. What are X and Y?
- 29. X – Matchsticks Y – Phosphorous

- 32. 15. Transplant The tree of 40 Fruits is an ongoing series of hybridized fruit trees by contemporary artist Sam Van Aken. The 40 fruit-bearing tree includes only "stone fruits" which all share very similar genetics. The tree looks like any other fruit tree for most of the year until spring, when it pops into pink, white and crimson blooms. In summer, the tree bursts with ripened fruit, including peaches, plums, apricots, nectarines, cherries and almonds. These are engineered using a fairly common gardening technique involving joining certain parts of a plant so that they grow together. What is this technique?
- 33. Grafting
- 34. 16. Capture the Flag Since the early days of the Internet, users have wanted to make text illegible to computers. The first such people could be hackers, posting about sensitive topics to online forums they thought were being automatically monitored for keywords. To circumvent such filters, they would replace a word with look-alike characters. This lead to the conception of _________, a type of challenge- response test used in computing to determine whether or not the user is human. This user identification procedure has received many criticisms, especially from disabled people, but also from other people who feel that their everyday work is slowed down by this test. It takes the average person approximately 10 seconds to solve a typical ________. Fill in the blanks. (Both blanks are the same.)
- 35. CAPTCHA (Completely Automated Public Turing Test To Tell Computers And Humans Apart)
- 36. 17. Friend J Priest B was an Indian nuclear physicist, who died when Air India Flight 101 crashed near Mont Blanc on 24 January 1966. Miscommunication between the Geneva Airport and the pilot about the aircraft position near the mountain is the official reason of the crash…but very soon after, a team of journalists led by René Desmaison climbed secretly near the wreck and declared to have found debris of another aircraft than the Boeing 707. Many possible theories have been advanced for the air crash, including a conspiracy theory in which the Central Intelligence Agency (CIA) is involved in order to paralyze India's nuclear program. ID B.

- 44. 20. Problem, Queen of Hearts? A mythical creature H had poisonous breath and blood so virulent that even its scent was deadly. Over the generations, various sources have given different versions of a particular characteristic of this creature. Later versions gave this creature a new ability R which made it a more formidable foe. A paradoxographer attempted to rationalize this myth by stating that this was an ordinary creature accompanied by its offspring so that it appealed to Christian apologists. A creature (not mythical) is now extensively being studied by scientists for the ability R. What are H and R?
- 45. H – Hydra R – Regeneration
