Beginner experiment of a capacitor holding a charge 

In this video, I demonstrate how a capacitor holds its charge after being disconnected from power. I found it hard to understand how this worked, and maybe this example video will help others by showing them how to try this in a simple hands-on experiment.
Equipment:
• FNIRSI DSO-TC3 Oscilloscope (amzn.to/4ejXIGu)
• Variable DC power supply (amzn.to/4c4JEi0)
• Analog IC kit (amzn.to/45gbMfK)
• ELEGOO Upgraded Electronics Fun Kit w/Power Supply Module, Jumper Wire, Precision Potentiometer, 830 tie-Points Breadboard Compatible with Arduino, STM32 (amzn.to/45kRxxC)
• InSwan overhead document camera (amzn.to/3VsZgoN)
Books:
• "Timer, Op Amp & Optoelectronic Circuits & Projects" by Forrest M. Mims III (amzn.to/3x5G0pf)
•"Electronic Formulas, Symbols & Circuits" by Forrest M. Mims III (amzn.to/4bUE5CZ)
Disclaimer: As I navigate through these circuits as a learner, please note that I'm not an expert. However, I believe sharing this example could be beneficial for others interested in electronics.
