Since these particles are microscopic then lifetime objects would be needed to demonstrate the moving of solid, liquid and gas........ For solid take anything like a chalk, pencil box, book etc........... For liquid you can take water, juice etc............. and for gas you can take perfumes, room fresheners, or sprays such as mosquito repellent etc....
