So you want to create your own clouds? Knowing a bit about physics and chemistry wouldn’t hurt your cause. The Oakland Toy Lab has posted a guide that shows how you can create your own instant cloud by re-creating the same process the clouds go through. You are going to need a bike pump, drill, water bottle, rubber stopper, and some alcohol to get started.
The good news is you don’t need to be a scientist to pull this project off. You can find more instructions on Instructables.com.
