We have had lots of fun pitching stuff into a 30 yard dumpster when we had one delivered. The first time we were in a seven story warehouse with stuff on the 7th and 4th floors. A stereo system dropped from the seventh floor can literally jump out of the dumpster upon impact. This was the first we tried. Containment works better when there is a little debris in the bottom. The first few items jumped right out of the dumpster, bouncing off the metal bottom. Of course they shatter when hitting the bottom making a mess to clean up when they jumped into the street. We did this on a Sunday morning, I recommend checking when your local authorities are not available. It makes a lot of noise and can attract attention. In NW Portland Oregon no one came by. After cleaning the street up of the first items we moved to the 4th floor where we had 60 Wang Terminal tubes to dispose of. These did not jump out of the dumpster. The fall from the 4th floor was not as great. They made a great pop when they hit the dumpster. It was a noisy morning. The Wang 2200 tubes were over 10 years old so it fits the criteria of the list, not to mention this was also in 1989, more than 10 years ago. It was before we realized the potential toxic hazard we were unleashing. Another time we had to despool several pallets of spooled wire. We took them up to the roof and dropped the spools into the neighboring parking lot. If you dropped them just right the spool would come apart and the coil of wire would rise up about 6 or 8 feet off the ground. Did not damage the parking lot. Lots of fun for work. A heavy aluminum or steel chassis will make marks in both concrete or asphalt. Plastic shatters making a big mess. We preferred to restrain ourselves until we had a dumpster to toss things into. Properly contained it can be a lot of fun. Paxton Astoria, OR
