Containers from used electric bulbs
Used electric light bulbs can be made into containers that will substitute for flasks, beakers, test tubes and same devices. With reasonable precautions these will stand considerable heat and handling. Any size electric bulb might be used. A variety of sizes will prove useful.
It is a wise precaution to wrap the bulb in an old towel or other piece of cloth whereas working with it. Begin by lifting the small metal button in the centre of the bulb top with a knife. Bend this up until it can be grasped with a pair of pliers. Raise this metal button by pulling upward on it with the pliers. This should expose the wire to which it is linked.
