My kid is learning about the solar system in their Kindergarten this week. What the planets are, sun is very hot, only earth has water, saturn has a huge ring, you travel with a rocket/ spacecraft..etc. Then they made this garland of various planets with rockets, asking us to hang it up on the ceiling, we obliged. It looked great. And guess what? It stayed up for 5 hours, longer than the one Ketamine Puffer fish sent up the other day. Choice.
