<xmlol> It really depends on the trajectory you are planning and the type of condiment in the jar. Here in Australia we use Vegemite jars, although the Nutella jar is also popular.
The majority of jar launcher crashes occur when the release mechanism is triggered but the jar is too firmly (or not firmly enough) attached to the device. The key is to make sure the lid is tight, and the bottom of the jar is wiped clean of all and any stickiness. A loose lid can lead to instability as the jar approaches escape velocity, causing havoc with the jar launcher's jar release mechanism. Sticky jar bottoms cause a similar problem. Having the correct density of condiment (eg Vegemite or Nutella) also play a major part in successful launches, where as the jams (jelly) and other toppings tend to be either too light or too dense, causing misfires and consequent launcher crashes. A secondary problem occurs when the jar launcher trajectory is too ambitious: any launch really needs to be between 27.5 and 67.5 degrees to the horizon, or the force vectors at the moment of release tend to reach a level of dissonanace that leads to a "dirty" jar release and subsequent launcher crash. Make sure you have the jar launcher tripod firmly locked into position on a firm, stable surface; have a fresh jar of suitably dense condiment, with the lid screwed on firmly and bottom surface wiped perfectly clean; remember to keep the trajectory angle reasonable and you should be fine. Good luck! </xmlol> ----- Original Message ----- From: "stylo stylo" <[EMAIL PROTECTED]> To: "CF-Talk" <[email protected]> Sent: Sunday, June 12, 2005 5:14 PM Subject: jar launcher crashes randomly > No one has ever heard of this? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Logware (www.logware.us): a new and convenient web-based time tracking application.
