Got a huge blow-up Earth and a styrofoam ball (DIY colour and draw Lunar surface details) to show the Earth-Moon relationship during sidewalk. This is the closest I could get to accurate scale with the Earth at 40cm in diameter and the Moon at 12cm in diameter.
One of its uses is to demonstrate the distance between them which people often misunderstand due to the cramped illustrations in textbooks and TV shows. At this scale, the Moon is about 13.2 meters apart from the Earth. Will be using a measuring tape to ask people to guess the distance between the two objects. Will be fun to see their reactions, especially kids.
