What can I do about corrosion on the launch ball for the Vernier Projectile Launcher?

We have discovered that in warm, humid environments, the balls included with the Vernier Projectile Launcher (VPL) can corrode. They are not stainless steel. They need to fit very precisely in the barrel of the VPL, so this can be a problem. Here are some notes:

- If you have this problem, let us know, and we can get you some Steel Balls (Set of 6), order code STB-VPL, $7.
- When not in use, keep the balls sealed in an airtight container such as a zipper closure bag. Consider including a desiccant packet in with them.
- Do not try using any kind of oil on the balls. The fit is very critical and oil will damage the launcher.
