Here is my very simple version of the Hertz experiment to show radio waves exist. The transmitter is a spark from a piezo lighter and the receiver is a neon bulb. The LEGO is just there for support (emotionally and physically)

I have these high voltage neon bulbs - they are pretty cool. Here's how to light one with a 6 volt battery and a transformer (bonus method uses a relay). #physics

j'ai aussi découvert qu'il y avait des expériences faciles à réaliser pour démontrer l'effet, avec un conteneur transparent, de l'eau, du lait et une lumière (ou des lasers, comme ici : www.youtube.com/shorts/RADtP... )
