Question

Inside a dark room, pull a strip

of Scotch tape from the roll
very quickly. What did you see?​

Answer 1

When you pull a strip of Scotch tape from the roll very quickly, a flash of light can be seen in the dark due to the triboelectric effect where the tape becomes electrically charged, creating a visible discharge.

Step-by-step explanation:

If you pull a strip of Scotch tape from the roll very quickly inside a dark room, you might observe a flash of light. This phenomenon is due to the triboelectric effect, which is where different materials become electrically charged after they come into frictional contact with each other. As you pull the tape, the adhesive side gets positively charged while the non-adhesive side gets negatively charged, leading to a buildup of electrical potential. When the difference in charge becomes large enough, a discharge can occur, producing a visible spark or flash of light. This is similar to a miniature lightning strike, where the quick motion of separating the tape creates enough energy to ionize the air particles and produce a glow that can be seen in the dark.

Answer 2

You didn’t see anything. The room is dark
