Make a Christmas-time glitter globe (aka snow globe)

In this science experiment we will mix molecules to make a glitter globe (i.e. a “snow globe”). We will combine rubbing alcohol, vegetable oil, and a few other tiny, shiny things to make a cool science toy.

An original Mathmos lava lamp, model "Astro", as it was sold during the 1990s

Lava lamps were immensely popular in the 1970’s. For some reason, your parents thought it was very fun to sit there and watch colorful liquid in a bottle swirl aimlessly around. They probably even chanted “Oh wow, the colors, the colors.

A graduated cylinder filled with various liquids to illustrate density

In our floating experiment, we touched on the topics of buoyancy. But in reality, flotation is also affected by other scientific principles as well. Here, let Geek Slop demonstrate…

Why does the oil float on the water rather than mixing with it? This experiment will take some of the mystery out of this phenomenon.

Vinegar, baking soda, food coloring, and a volcano made of dough

In this experiment we will build a real working volcano. After mixing just the right amount of ingredients together, we’ll add the final item to make our volcano ‘blow its top’ spewing red lava down the sides. Yes, this is the famous “Baking Soda Volcano” experiment – found exclusively at Geek Slop (and on the…
