Part 1 - Las Alas Del Diablo and your picture on the wall If you don't finish them, the contract says you donate a hundred bucks to the local food bank." Contract?" "The contract you sign if you order the wings. Don't worry you don't need to sign in blood or anything. We use hot sauce." "Go on Phil, get the wings. You love hot stuff!

'A waitress comes to take their order "Can I take your order?" Ya, I'll have the beef enchilada and a Coke." And you? What is this Las Alas Del Diablo?" Just like the menu says, devil's wings.

The menu says they are a hundred bucks, that can't be right?" "Well, sort of Ifyou finish all six in fifteen minutes they are free, and you get a milkshake,Explanation / Answer
Many plants have ripe, fleshy, coloured fruit in order to attract animals that will eat them and then disperse their seeds in droppings. However, the chilli plant has developed another way of ensuring its seeds are spread far and wide.
What raises the roof of your mouth when you eat a chilli is a substance called capsaicin. This stimulates the areas of the skin and tongue that normally sense intense heat and pain, falsely telling the brain that the area affected is burning.
when birds ate the chillies, many seeds germinated, but there was no germination after mice had eaten the chilli seeds.
This is thought to be because seeds pass through a birds’ digestive systems very quickly and come out unharmed, whereas in mice, rats and other mammals, the seeds don’t make it out in one piece as they are broken down by the acidic juices during digestion.
There is tremendous evidence that spices are anti-microbial. Of 30 commonly used spices, at least half of them kill or inhibit 75% of the bacteria they have been tested on.
