Tips |
- Be careful not to get the sphere stuck in or through the hole! Once the ball is stuck it is difficult to heat the plate enough to extract without also heating the ball so much that it expands too.
- Using the propane torch (by the red toolbox or shelf 57), heat the aluminum plate for ~1.5 minutes. Once the plate is hot enough, the hole in the center will be large enough to allow the sphere (from the “ball and ring” demo 074) to pass through. The sphere can pass through the hole for ~30 seconds.
