Bending Light Through Liquids
Light only travels in straight lines, but we can get it to bounce around a bend.
Steps
Step #1:
Next
- Click the upper left corner of the comic to view full size!
- Carefully cut a 1/2" (1.5cm) hole in the lower third of the bottle.
- Punch or cut a hole in a piece of duct tape. align the two holes and stick the tape to the bottle.
- First, pour several drops of milk into the bottle. Then fill it up with water. Be sure to plug the hole with your finger. The mix should be cloudy but see-through.
- Once the bottle is full, cork the top (or screw on the cap) and remove your finger. The water will stay in the bottle until more air is let in through the top.
