DIY science is the perfect way to use your creative skills and learn something new. With the right supplies, some determination, and a curious mind, you can create amazing experiments that open up a whole world of possibilities. At home-made laboratories or tech workshops, makers from all backgrounds can explore new ideas by finding ways to study their environment in novel ways – allowing them to make breathtaking discoveries!
Piezoelectric materials are about as close to magic as you can get. They turn physical pressure into electricity and can even turn electricity into physical pressure – an amazing sort of bidirectional converter for mechanical and electrical energies. Perhaps even more amazing is the fact that you can easily ‘grow’ your own piezoelectric crystals overnight using just a couple of common ingredients – awesome.

The claim of penetrating a razor-blade impresses me, although I note the only metal penetration in the video is thin aluminum, which has been painted, possibly so that it will absorb more light energy. Thereโs also some cool shots capturing the pulsed-laserโs plasma ball in midair.
To me, public libraries โ the availability of free education for all โ represent the collective commitment of a community to their future. They symbolize what is most important, a commitment to educating the next generation. The role of a public library should also adapt over time, and that time is finally here. It’s time […]
These covert cameras employed by wildlife videographer John Downer imitate natural elements of the Arctic Norwegian environment to grab an insanely closeup view of the polar bear’s journey. Jacob Resneck at Cool Hunting writes: Downer employs three types of cameras to track the lives of two mother bears as they lead their clubs across Arctic […]

Chad’s a former student of mine who has been doing electric car projects for about six years now. On seeing The Cap Kart project, he says:
If you were to start an electric vehicle school program, I would start by following these guidelines to build an electric go-kart! It looks like they got everything donated and therefore kept the overhead down. After doing this you could challenge other schools in the area to a race. Also, this would be a great stepping stone for moving towards a full vehicle!!
