This may not even exist, but I seem to recall a company, possibly a battery company (Duracell? EverReady?) runs a heavily promoted science fair either based on their product or merely sponsored by it. It’s not Toshiba/Exploravision, though that’s pretty similar to what I’m thinking of. If it exists, I figure we probably have some past winners here (or at least entrants) so thought someone would be able to help rid that nagging feeling of aphasia.
Thanks!
