The activity can be viewed at: Turn Milk into Plastic

Hello,
That seems like a really cool theme! I would recommend this experiment: https://www.sciencebuddies.org/stem-act ... to-plastic
It explores how bleep from nature, milk, can be turned into plastic, definitely a hidden language.
Hope this helps!
