the floor. He climbed down quickly, expecting to find broken glass everywhere, but he was in

for a surprise. The bottle hadn’t shattered into pieces! It had cracked into a spiderweb-like

pattern, but it had held together. Bénédictus wondered why. 5.1. _____ Although it had been

washed before being put back on the shelf, Bénédictus realized some of the liquid plastic

must have remained inside as a thin invisible coating. It had kept the cracked glass from

falling apart.

The same week, a Paris newspaper printed an article about car crashes. The automobile

was a new and exciting invention, and more and more people were taking to the road.

The article blamed the collisions on the poor condition of the roads. 5.2. _____. Bénédictus

wrote in his diary, “While I was reading the article, an image of the cracked bottle suddenly

appeared in my mind.” Could his accidental discovery be somehow useful?

He ran to his lab and started experimenting. 5.3. _____ However, the results were

disappointing. Finally, he put a layer of liquid plastic between two sheets of glass and

pressed them together. When he hit it, the glass-and-plastic sandwich cracked, but it didn’t

smash into pieces. Bénédictus had done it! He wrote, “I had produced my first piece of

Triplex (his name for the invention) – full of promise for the future. Hopefully, driving a car will

be safer with the new glass installed.” 5.4. _____ The kind of liquid plastic used to make

safety glass has changed since Bénédictus’s time, but his method of putting it between

sheets of glass is still used today. Even bulletproof glass is made of layers of glass and

strong plastic.

growing.

C. Over and over again he coated single sheets of glass with liquid plastic and hit them with

liquid plastic during some experiments.
