Abstract: This application relates to improvements in environments for microbial testing. Exemplary embodiments provide a uniquely configured tray containing an environment conditioning material, such as an oxygen scavenger material, for use with a cassette assembly. Furthermore, some embodiments provide a cutting mechanism that allows the tray to be reliably breached, thereby exposing the material inside to the environment. Some embodiments can cut open the material with specially-configured cutter teeth, which can easily be deployed by twisting or pushing two halves of the cassette assembly.

Abstract: A baseball bat may be provided as part of a baseball training kit and a method of training a baseball player. The bat may include an internal tube sized to accommodate a plurality of cylindrical weights. Similarly sized cylindrical spacers, having significantly less mass than the weights, may also be inserted into the internal tube. Players can select different weight resistances by selecting which of a plurality of spacers and weights should be inserted, and in which order. A cap may be provided proximate the handle in order to secure the weights and spacers within the internal tube.
