The Backyard Scientist channel may be lean a little towards the "let's blow some stuff up because it's cool" but he does do some practical projects that are fun to watch. Now that I have a backyard I am seriously thinking about trying some of his projects out for myself.
Here are a few of the more interesting projects that the Backyard Scientist has done.
Molten aluminum in water beads.
Ping-pong steam engine (with liquid nitrogen).
Sending a GoPro to space.
Did you know molten salt explodes when it comes in contact with water?
Wood etching/burning with lightning.
There are plenty of "let's blow stuff up" channels on YouTube, but the Backyard Scientist tries to do science in the same style as the MythBusters. It may be for entertainment, but there is a commitment to be curious and to explore, and to test ideas and see what works. So it may not be publishable science, it does stay true to the idea of scientific exploration.
There are also a few cool ideas that would be fun (and safe) to try with young children. So if you need ideas for fun summer projects to help your children learn this is a good place to get a few ideas.
As a safety note: having worked with a few dangerous substances, and electricity before, the Backyard Scientists do not always take the best safety precautions. So as with anything hot, explosive, electrical, corrosive, or toxic, know the hazards and use common sense. But don't let that stop you from trying.
