Protecting Equipment from Children

 I never really thought about it and raised 3 kids on my own. They never screwed with my stereo. Funny thing though in later years I waited until everyone was out of the house before I would listen to music.

 THEN, one day my first grandkid visited. Went right for the stereo. Became a sort of game which I hated.

@geof3 nailed it. Constant surveillance. There is no substitute. 

My grandson stuck Play Doh into the rear port of a speaker and ran off.  Only his three year old hand/wrist could fit into the port and he wasn’t interested in retrieving it.  On the other hand, the Pay Doh was revelatory, as if a veil had been lifted, and I now recommend it to everyone as a tweak

Just how big a load of Playdough are we talking here? Multiple trips or just a handful? You may never know.

How far into the port?
