Blueprint
The blue-print was invented in 1840 by John Herschel using a mixture of ferric ammonium citrate and potassium ferricyanide to produce a pare that is light sensitive. It was popular among amateurs in the nineteenth century because it was relatively simple and required no development or fixing, just washing. It has also been used my engineers as well as architects for technical drawings. -

The Saftey Pin was invented by Walter Huntt when he was twisting a piece of wire and trying to think of a way to pay off a fifteen dollar debt. Walter's sftey pin was one piece of wire coiled into a spring at one end and had a clsp on the other end. His first pin allowed the point of the wire to be hidden inside the clasp.

Ironclad, Turtle Ship
The Japanese attempted invasion, so, the Korean Naval designed a ship to defend themselves. The dragon head was large enough for a cannon to fit inside. It also had many spikes and cannons on all flanks to make it even stronger and harder to get onto. Early versions of the turtle ship would burn poisonous materials in the dragons head to release a poisonous smoke. It was designed to help the Korean Naval defend their lands.
