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. 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 a

How capillary action makes water go up…

How capillary action makes water go up... Even though we usually think of water as running downhill, it can indeed flow upwards using a process called capillary action. This is the very scientific principal that explains how water goes from the soil upwards into the stem of plants. Plants contain many vein like tubes that carry water from the plant's roots upwards to the plant's highest leafs via capillary action. Try this experiment to see capillary action in action. Wrap the plastic wrap around the knitting needle and then tape the edges so that you have formed a tube. Remember, the narrower the tube, the more pronounced the capillary effect will be. Once you have taped the plastic wrap, pull out the knitting needle. Make sure that the

Homemade Barometer experiment

Homemade Barometer The air pressure around us greatly affects our weather. Notice how your weatherman always mentions various pressure systems (low pressure system, high pressure system, etc.) and how they will affect tomorrow's weather. In this experiment, we will create a tool that lets you gauge the pressure of the air around you. Fill the measuring cup or glass with water and add some colored dye to it. Flip the empty soda bottle upside down into the glass measuring cup. Make sure that you use a bottle that is just the right size. The thicker body of the bottle should fit snugly in the measuring cup so that the mouth of the bottle does not touch the bottom of the cup. Make sure that the level of the water extends

Yep, you heard right. Make a homemade tornado

[sc:commonscripts] This tornado experiment will blow you away! A tornado is a powerful, twisting windstorm (now that really does sound like Dad, doesn't it). The winds of a tornado are the most violent winds that occur on the earth. They whirl around the center of the storm at speeds of more than 200 miles per hour (and that's faster than Dad running to the bathroom during a commercial break). A tornado is a rotating funnel cloud that extends downward from a mass of dark clouds. Some funnels do not reach the earth. Others may strike the surface of the earth, withdraw into the dark clouds above, and then dip down and strike the earth again. In this science experiment, we are going to recreate a tornado -

Splatter blood for blood spatter analysis

Splatter blood for blood spatter analysis First we will let you in on a little secret. When you or your brother or sister do something wrong, your parents have to figure out who did it. To parents this is like a whodunit game and in fact, they have a secret name for it that they have sworn never to reveal to the kids (breaking this rule can result in loss of their official parenting card). It’s called the “which kid do we smack this time” game. And no, they don’t roll dice or draw straws to figure it out the winner. Parents have an eerie, almost superhero-like ability that allows them to scan human faces to determine the guilty party. It worked so well that a long

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 full

Silly Putty or slime experiment (your choice)

Fine times with homemade slime (or silly putty if we tweak it up a bit) At some point you may have heard someone speak of “polymers”. A polymer is a large molecule that is made of repeating structural units. These units are connected by what is called a covalent chemical bond. A well known polymer is “plastic”. In this experiment, we will make a polymer and then add a substance that will cause the polymer chains to cross link. Cross links are bonds that link one polymer chain to another. When the polymer chains are more “bound together”, they become harder to move around and begin to gel. In a bowl, mix an equal quantity of Elmer’s glue and water. Fill a jar with a cup

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 colored water. Pour some rubbing alcohol

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 the soda bottle

Elephant Toothpaste

Help an elephant with those 9-pound molars So you don’t want to be a kid and instead want to be an elephant because Reeko said elephants never have to brush their teeth? Well Reeko has news for you – there’s a lot more differences between kids and elephants than just their teeth. If you don’t believe that, try picking one up. Imagine being an elephant and always loosing at hide and seek. Even when dressed in yellow and disguised as a banana they are easy to find in a crowd. They are large, gray, and wrinkly. And when they do brush their teeth – well, those are 9 pound molars they have to deal with. Now that we have your elephant yearnings out of the way,
