This is the prototype RGB LED Time Fountain I designed and built. It uses RGB LED strip lights to strobe a stream of water drops to make them appear as if they are levitating. By strobing the different colours out of phase with each other some incredible effects can be created. An Arduino Uno controls the timing of the RGB strobe and the PWM of the pump. Bluetooth communication was achieved using an HC-05 Bluetooth module and the "Arduino bluetooth controller" app by "Giumig Apps". The code…

You probably know that objects sink or float in water depending on their density. But did you know that liquids can sink and float, too? In this activity, you will create a colorful liquid density column by stacking different liquids on top of each other. How many layers can you create? Written instructions are available on our website at https://www.sciencebuddies.org/stem-activities/liquid-stacking-density?ytid=lYITnkFxa5A&ytsrc=description Science Buddies also hosts a library of…
