Color changing milk experiment

Science Night The Explosion of Colors Experiment – This experiment is a lot of fun. How does it work? Milk has fat in it and the food coloring floats on top of the fat. The fat is all connected with bonds. When you add the dish soap to the milk, the fat separates and moves making the colors explode!  

Amazing Melting Ice Blocks Experiment

Totally Awesome to Watch!!! This is one of the most striking science demonstrations we have seen in a long time. Place an ice cube on each of these two identical looking black blocks at room temperature. One ice cube instantly begins to melt and is totally gone in about 120 seconds while the other ice cube shows no evidence of melting.  

Skittles Experiment

Colorful candies like Skittles are made with FD&C dyes, sugar and other substances. By adding hot water with the skittles it starts to release the dyes as you can see here with the experiment.   Try different candies to see if you get the same results. Or start the candy in the middle of the plate to see what happens. Best part is you can still eat them.  

Floating Paper Clip Experiment

How is this possible? With a little thing we scientists call SURFACE TENSION. Basically it means that there is a sort of skin on the surface of water where the water molecules hold on tight together. If the conditions are right, they can hold tight enough to support your paper clip. The paperclip is not truly floating, it is being held up by the surface tension. Many insects, such as water striders, use this “skin” to walk across the surface of a stream.  

Drops of water on penny

How Does It Work? Surface tension gives water some amazing properties. The cohesion and surface tension of water becomes apparent when the drops of water you add to the penny reach the penny’s edge. Once the water has reached the edge, you begin to see a bubble or dome of water forming on top of the penny as you can see here in the video. The bubble shape is a result of the water molecules clinging to one. I was able to get 30 drops on a penny. Let me know how many you were able to do?  

Iodine Clock reaction

First you Make two chemical solutions and mix them together. Wait a few seconds, then wow! It will suddenly change colors. This is the famous iodine clock reaction in an easy-to-use kit. Change the concentrations or temperature and change the delay for the color change. Adult supervision is Required.  

Tornado Tube experiment

The Tornado tube Connector is a plastic adapter fitted for two plastic soda bottles to be held together to create a vortex within one of the bottles. It works by flipping and then spinning the bottles in such a way that the water is now in the top bottle and the air begins to replace the water in the top bottle in a vortex shape.
