I&#x27;m sorry but.. safety procedures (and training), paperwork and thorough tracking of substances are a huge part of actual experimental science. Yes it may be discouraging that a young child can&#x27;t just go and do the experiment they want unhindered but that&#x27;s not how safety works. Even mundane non-cleanroom handling isn&#x27;t allowed until the right safety training is taken (yearly basis).<p>P.S. Yes I&#x27;m aware a number of these chemicals can be picked up locally at Home Depot etc. to be &quot;played&quot; with at will, but this doesn&#x27;t negate how public-funded experimental research is done.
