THE INVENTION OF POPSICLE

The Popsicle was invented by an 

11 year 

who kept it secret for 

18 years.

The inventor was Frank Epperson 

who, in 1905, left a mixture of powdered soda and water out on the porch, which contained a stir stick. 

That night, temperatures in San Francisco reached record low temperature. 

When he woke the next morning, he discovered that it had frozen to the stir stick, 

creating a fruit flavored ice treat that he named the epsicle. 

18 years later he patented it and called it the Popsicle.

INVENTION OF VELCRO

A dog invented velcro.

Swiss engineer George de Mestral 

was out for a hunting trip with his pooch, 

and noticed the annoying tendency of burrs to stick to its fur 

(and his socks). 

Later, looking under a microscope, Mestral observed

the tiny "hooks" 

that stuck burrs to fabrics and furs. 

Mestral experimented for years with a variety of textiles before arriving at the newly invented nylon—though it wasn't until two decades later that NASA's fondness for velcro popularized the tech.

INVENTION OF X-RAYS

The story of their discovery is a fascinating 

one of incredible chance. 

In 1895, German physicist 

Wilhelm Roentgen 

was performing a routine experiment involving cathode rays, 

when he noticed that a piece of fluorescent cardboard was lighting up from across the room. 

A thick screen had been placed between his cathode emitter and the radiated cardboard, proving that particles of light were passing through solid objects. Amazed, Roentgen quickly found that brilliant images could be produced with this incredible radiation—the first of their kind being a skeletal image of his wife's hand.

DISCOVERY OF MICROWAVE

Microwave was discovered accidentally, when a chocolate bar melted in Percy Spencer’s pocket

 The fact is, Percy LeBaron Spencer of the Raytheon

 Company was walking past a radar tube 

and he noticed that the chocolate bar in his pocket melted. 

He then tested popcorn in front of the tube  

and it quickly popped all over the room. 

SUPER GLUE

 Super Glue is invented by Harry Coover

In what have been a very messy moment of discovery in 1942, Dr. Harry Coover of Eastman-Kodak Laboratories found that a substance he created
cyanoacrylate
was a miserable failure. 
Six years later, while overseeing 
an experimental new design for airplane canopies, 
Coover found himself stuck in the same gooey mess 
with a familiar foe
cyanacrylate 
was proving useless as ever. 

But this time, Coover observed that 
the stuff formed an incredibly strong bond 
without needing heat.
 Coover slapped a patent on his discovery, and in 1958, a full 16 years after he first got stuck, cyanoacrylate was being sold on shelves.

PEANUTS TO MAKE DYNAMITE!!!!!!!

Dynamite is made with peanuts

Peanut oil can be processed to produce glycerol, which can be used to make nitroglycerin, one of the constituents of dynamite. Note however, there are other processes that can be used to make dynamite without using peanuts at all.

GREAT INSPIRATION

The Bullet proof vest is invented by a 

pizza delivery guy 

from Detroit, after he was shot twice on the job.

COCA-COLA

 Coca-Cola contained Coca 

(whose active ingredient is cocaine) 

from 1885 to 1903.

Coca-Cola would be green if colouring weren’t added to it.

REFRIGERATOR BY EINSTEIN

Albert Einstein invented a refrigerator that operated on 

alchol gas in 1926. 

Einstein invented the refrigerator because he read about a family

that was poisoned by a

sulphur dioxide emitting refigerator.

But never went into production.

WORLD'S LIGHTEST MATERIAL

GRAPHENE AEROGEL is the world's lightest material.

It is SEVEN times lighter than AIR, can balance on a blade of grass.

FIRST ARMORED CAR

LEONARDO DA VINCI

is the first person to drew the plans for the first ARMORED CAR in 1485.

He also designed the cannon, machine gun, gliders, turn-spit for roasting meat, canal system to irrigate fields, and invented the parachute.

INVENTION FOR SAFETY

The CONDOM was invented in the early 1500s

and is made originally of linen(its a type of fabric).

A BRIDGE WHERE A BOAT CAN SAIL UNDER TRAIN, CAR, AIRPLANE

The Boston University Bridge 

(on Commonwealth Avenue, Boston, Massachusetts) 

is the only bridge in the world 

where 

a boat can sail under a train 

a train driving under a car

a car driving under an airplane.
