glow in the dark?

Purpose

Hypothesis

By: Kodi Bell

My hypothesis is that the highlighter will glow.

Highlighter

Cup

Highlighters glow under a black light because of the fluorescence in its ink.

Water

Black Light

Procedure

  • Black light is only black because not a lot of the light of the lamp is in the visible spectrum.
  • The materials glow because of fluorescence: absorbing the light and transmitting it at another frequency.
  • Most is actually UV light.
  • We cannot see UV light but we can see the retransmitted visible light causing the object to glow.

Research

Step-by-Step Directions:

Step 1: Pour water in cup.

Step 2: Remove cap from highlighter.

Step 3: Place highlighter in cup.

Step 4: Turn on the black lights.

Step 5: See if the highlighter can make the cup of water glow.

Conclusion

Results

The conclusion is that in black light the highlighter can make water glow.

The black light shined on the cup and you could see a bright yellow glow coming from the water around it.
