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

Make your own amazing 3D printed optical illusions based on the work of Professor Kokichi Sugihara, including the "impossible arrow" and other shapes! These illusions exhibit "anomalous mirror symmetry" where their reflections appear flipped left to right in a mirror. Instructions and working example code in both MATLAB and Python are available on the Science Buddies website:…
Make a battery with pennies, nickels, salt, and vinegar in this fun science experiment! This type of battery is also called a voltaic pile. You can use a multimeter to measure the voltage and current produced by your battery, and even use it to light up an LED. Written instructions for this project are available on the Science Buddies website: https://www.sciencebuddies.org/science-fair-projects/project-ideas/Energy_p015/energy-power/make-a-battery-from-coins?ytid=JcRRTHkAl6A&ytsrc=description…
Candle carousels, or Christmas pyramids, are part of the German Christmas tradition. It is fun watching them spin around like a merry-go-round. But why exactly do Christmas pyramids spin? There is no electricity, just candles! In this video, you will build your own candle carousel and investigate how the candle’s heat makes the candle carousel rotate. Written instructions are available on our website at…
