We’ve all played with bubbles, but are there ghosts inside of yours? Jason Lindsey aka “Mr. Science” with Hooked on Science shows us the science behind “Ghost Bubbles.”

INGREDIENTS

n Rubbermaid MixerMate Clear

n 2qt Bottle w/ Chili Red Lid

n ½” Vinyl Tube

n Dishwashing Liquid

n Warm Water

n Dry Ice

n Fuzzy Glove

INSTRUCTIONS

n STEP 1: Attach the ½” vinyl tube to the Rubbermaid MixerMate clear 2qt bottle chili red lid.

n STEP 2: Pour warm water into the Rubbermaid MixerMate clear 2qt bottle, add a few pieces of dry ice, and then secure the chili red lid onto the Rubbermaid MixerMate clear 2qt bottle.

n STEP 3: Place the fuzzy glove on your hand, put the end of the ½” vinyl tube into the dishwashing liquid, and hold the ½” vinyl tube over your hand allowing the bubble to fall on the fuzzy glove.

n STEP 4: Pop the bubble and observe.

EXPLANATION

When dry ice is placed into the warm water a cloud forms. Dry ice is frozen carbon dioxide gas and is -109.3°F. As dry ice breaks down it turns directly into carbon dioxide gas. In science this process is called sublimation. The bubbles are filled with the cloud, which is created by the dry ice sublimating. When you “pop” the bubble the cloud rushes out, which looks like a ghost.
