A Better Way to Organize Laboratory Equipment

I decided to take the time and to do some needed inventory.  I wanted to match equipment to its designated table.  Next, I wanted to make sure that each of my eight lab tables had the proper equipment needed to eliminate no more missing equipment.  Sure enough, as I began the inventory project, I had several tables missing equipment, so once everything was laid out and counted and organized then I had to make sure it was going to stay that way.  I had several rolls of colored tape and it was easy to then begin marking each of the pieces of equipment and glassware with tape.
