Vintage children's PSA on explosive safety

If you grew up in certain areas of the country, you may have been subjected to a lot of education about the dangers of blasting caps, like this PSA by The Institute Of Makers Of Explosives.

These fun-looking primers sometimes ended up on the ground near blast sites at farms, construction sites, mines, quarries, and so on.
