At the Sderot police station there is a collection of hundreds of Gaza rockets that have landed in that town over the years. Here is a panorama photo of some of them. Click to enlarge.
On the left side is a glass case of more notable rockets, like the ones that have the name of the terror group painted on them, or some of the larger Grad missiles.
Nowadays most of the rockets are more "professionally" made - calling them "home-made rockets" is less appropriate than it used to be. The now rusting Sderot rockets are more of a lesson as to what lengths terrorists would go to in order to target Jews.
Many of the rockets are clearly made out of pipes meant to help Gaza's water issues.
