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

In this science experiment we will mix molecules to make a glitter globe ( a "snow globe"). We will combine rubbing alcohol, vegetable oil, and a few other tiny, shiny things to make a cool science toy. How to make a glitter globe Fill a clear plastic or glass bottle 1/4 full of rubbing alcohol. Add one drop of food coloring if you want to give the liquid mix some color (and make it easier to differentiate the alcohol layer from the layer of oil that we will add next).Note: if you want to use your snow globe for decorative purposes, skip the food coloring altogether. Fill the remainder of the bottle with baby or vegetable oil (the oil will sit on top of the alcohol).  Leave…

Make a homemade Lava Lamp experiment

Make a homemade Lava Lamp Lava lamps were very 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.” They became popular again a few years ago but as we know, kids today are much smarter, and thought that lava lamps were cool because they knew they demonstrated the scientific principles of immiscible liquids (liquids that just won’t mix). In this science experiment, we’ll create a real working lava lamp and explain to your parents why they really should be thought of as cool. Fill a glass jar with 3 inches of water or until it is 2/3…

The ‘Am I Dense’ experiment

The 'Am I Dense' experiment 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 Reeko Pour one-third cup of syrup into the glass jar. Now pour one-third cup of cooking oil into the jar. Finally, pour one-third cup of water into the jar. Let the contents settle for a few minutes. Drop a piece of plastic, a grape, and a small cork into the liquid. Notice how the objects you dropped in settle down to different layers of the mixture. The liquids have different densities. The most dense (syrup) will be at the bottom, the least dense (oil) will be at the top, with the water in between.…

Oil and water don’t mix

Immiscible liquids, like oil and water, don't mix After a rainstorm have you ever noticed puddles in the road with glossy-looking oil floating on top? Ever noticed the oil spots that sometimes form in your chicken-noodle soup? Ever notice how Reeko occasionally writes 'lead ins' to the experiments that have absolutely nothing at all to do with the experiment? 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. Take a jar of water and put a drop of food coloring in it (Reeko prefers blue ). Now pour in some vegetable oil. Next stir or shake the jar. Do the oil and water mix? Finally, take another jar of…

Look out, she’s gonna blow!

The infamous baking soda volcano experiment Now we're going to get a little messy. In this experiment we 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 Reeko’s Mad Scientist Lab (and on the websites of the millions of Reeko’s minion slaves). First we need to create the 'salt dough'. Mix 6 cups flour, 2 cups salt, 4 tablespoons cooking oil, and 2 cups of water in a large bowl. Work the ingredients with your hands until smooth and firm. Add more water to the mixture if needed. Stand…
