How We Make Glass Nearly Unbreakable … With Science

The video explores the properties of glass, explaining why it is both fragile and strong. It delves into the nature of glass as an amorphous solid, highlighting its molecular structure and the reasons for its brittleness. The video then discusses how tempered and laminated glass are manufactured to enhance safety, particularly in car windows. It further explains the construction of bulletproof glass, which combines layers of glass and plastic to stop bullets. The video concludes with a call for further innovations in glass technology.

What is the term used to describe the unique solid state of glass?

• Crystalline solid

• Amorphous solid

• Polycrystalline solid

• Liquid crystal

Why is glass transparent?

• It reflects all visible light

• Its disorganized molecules do not absorb visible colors

• Its molecules are highly organized

• It absorbs all visible colors

What happens when glass is hit at its weak points?

• It changes color

• It bends without breaking

• It forms a tiny crack

• It becomes more transparent

How is tempered glass made stronger than regular glass?

• By cooling it slowly

• By heating it to a higher temperature

• By adding metal reinforcements

• By forcing the outer layer to freeze first

What is a key safety feature of tempered glass when it breaks?

• It remains intact without breaking

• It melts into a liquid

• It explodes into dull-edged clumps

• It shatters into large sharp pieces

What additional layer is used in laminated glass to enhance its strength?

• A thin sheet of plastic

• A layer of rubber

• A layer of metal

• A layer of wood

What material is often used in bulletproof glass to reduce weight?
