Spark Bang Buzz
The
Spark Bang Buzz website has not been updated in a while (it posts that the last entry was August 2004) but there is lots of neat cool stuff there.
Among the entries are these examples:
A
Propane Powered Lawnmower
A
Homemade Photocell
Extracting
odd sounds from salt water and Aluminum
Making
your own Vacuum Tube
Fun stuff -- I'll be trying the salt-water/Aluminum sounds in a few days.
