Glass blowing, if you didn't know, is the art of working with molten fucking glass to make your very own glass containers. Oh, and you do it by blowing into a wad of molten glass with your mouth. Bizarre as it sounds, glass blowing was considered a useful skill for a young man to have half a century ago. Universities actually, once they were done carving their desks out of lumber.

They'll be fine if they don't inhale. Keep in mind that in order to be able to change the shape of the glass, first it has to reach its softening point, which is. The Gilbert Glass Blowing Set encouraged children to try this with their bare hands in order to carry out a series of detailed in the manual: We did find that when the glass becomes red hot it removes all the skin from our hands. In 1843, realizing that boys might want a toy train that did more than just sit there, the Stevens Company created the, one of the first ones that actually moved. Of course, the main reason why toy trains didn't move up to that point was simply that the technology didn't exist.
The Model Dockyard Locomotive got around that limitation by using a real steam-propelled engine that required kids to pour either kerosene or alcohol into the train and then light it. It also comes in a 'battered pipe-bomb' edition. But wait, that's not the dangerous part yet. The toy steam engines of this era were nicknamed 'dribblers' or 'piddlers' because they tended to as they rolled along the floor. This safety hazard didn't stop the Model Dockyard Locomotive from becoming a popular children's toy in England back then, mainly on account of the strength of its ' Fuck safety! 
This thing fucking moves!' Thankfully modern action cinema has made us aware of the dangers of leaking fuel.
Also, at this point toy trains didn't even have tracks, so kids could just set them on a path of destruction across the house and then light the kerosene coming out of the back, leaving a blazing trail of death. (Or at least that's totally what we would've done.) The fire speaks to us. The blades in that circular saw up there probably aren't sharp enough to pierce through a human skull, but still, we dare you to find a used set on eBay that doesn't come decorated with suspicious red stains. But hey, you can also use them as ninja stars! Another winning Powermite product was the, which looks like a hamster-sized version of a James Bond death trap (and was probably used as such). If mutilating himself or others wasn't enough, a boy could also 'play' with the Powermite. Note that the sabre saw comes with a spare blade, in case the first one has been dulled by bone.
