TEST Why It Was Almost Impossible to Make These Inventions

Let's make a video that discusses different inventions that were almost impossible to make, but after years or centuries, scientists managed to find the answer and the video could discuss the challenges faced in their development. 1) Blue LEDs. LEDs do not get their color from their plastic covers, but rather from the electronics themselves. The video could explain that blue LEDs were difficult to create, and for decades, only red and green LEDs were available. The ability to create blue LEDs would allow for the mixing of red, green, and blue to create white, unlocking the use of LEDs for various types of lighting that is why scientists were eager to find a solution. 2) Graphene - Scientists already knew about the theoretical existence of materials comprising single atomic layers but no-one had previously been able to isolate one. Since 1859 scientists had been trying to achieve a single layer using chemical and mechanical methods involving expensive and specialised equipment. However, when a single sheet of graphene was finally isolated, it was done using a cheap and familiar piece of equipment—ordinary sticky tape. 3) Flying machines: Though da Vinci's detailed sketches captured the world's imagination, achieving flight required advancements in materials like lightweight metals and powerful engines, things the Middle Ages simply lacked. 4) Touchscreens: The concept of a responsive touch interface on electronics existed for decades, appearing in sci-fi movies and novels. However, the technology to reliably detect and interpret finger touches on screens took considerable time to develop. 5) Artificial diamonds: Diamonds have captivated humanity for centuries, but creating them artificially seemed impossible. Scientists understood the basic physics involved, but replicating the extreme pressure and temperature conditions under which natural diamonds form proved formidable.
