Put a nickel on top of a quarter. Or, use whatever coins you have with the top one smaller than the bottom one. Hold them above your other hand. Drop them. They will rotate and reverse places. Get the distance just right and they will land softly in your lower hand. Great party trick. 🙂
I used my Samsung Galaxy s5 to film this at 1/8 speed. YouTube allowed me to trim out some dead time and shorten the video. It also did some minor enhancements to lighting and color.
After a year of using the phone, it was time to try some unused features. I am not an avid phone user.
