SEEDER
Jethro Tull was the one who invented it.
Now it has been improved much more than when he invented it and it is used to sow and not go one by one and take a long time.
Thanks to this device, more crops were grown, people ate more, and the economy also rose because more and more food was sold. -
MERCURY THERMOMETER
Daniel Gabriel Fahrenheit was its inventor.
A mercury thermometer is a type of thermometer that is generally used to measure temperatures of selected material.
I help them to know the exact temperature of some materials. -
LIGHTNING ROD
Benjamin Franklin was the one who invented it.
A lightning rod is an external terminal installed on a building or structure that aims to attract lightning to have a controlled impact point and prevent it from hitting an unwanted area or causing damage to people. -
HOT AIR BALLOON
Montgolfier brothers were the ones who invented it.
Its function is to fly and take walks in the sky. It is a means of air transport, because it moves through the air. It is considered a type of ship that allows movement, although this is merely recreational and temporary, since it does not fulfill the function of regular transport. -
STEAMBOAT
John fitch was the one who invented it.
The boats have a hollow metal tube in the shape of a serpentine and a sail, with which the water inside the metal tube is heated and turns into steam. As the vapor occupies more space than the liquid water, an expansion is generated, which pushes the water out of the tube at the back of the ship. -
SEWING MACHINE
Thomas saint was the one who invented it.
A loom is a weaving machine that makes cloth. It can be powered by human energy, by water, or by some kind of engine. Most looms today are mechanical, powered by electricity, but for most of human history they were powered by the human body. -
GAS TURBINE
John barber was the one who invented it.
Air enters through the turbine intake. The compressor increases the pressure of the air before it enters the combustion chamber. This compressed air is then mixed with fuel and ignited, creating a hot gas that expands. -
PENCIL
Nicolas-jacques conté was the one who invented it
A pencil is a writing or drawing instrument that features a graphite rod enclosed in a cylinder of wood or other material. In this way, it is possible to take the cylinder by hand and move the graphite tip on a paper or other similar surface to mark the lines and write or draw. -
HYDRAULIC PRESS
Joseph bramah was the inventor.
A hydraulic press is a mechanical device that uses the flow of fluid (usually hydraulic oil) to generate force and is used to compress different types of materials to compact and ultimately pack them. -
VACCINE AGAINST SMALLPOX
