Dangerous shards of glass from broken light bulbs could soon be a thing of
the past. British company Fotolec is making 鈥渦nbreakable鈥� domestic light bulbs
by coating them with a clear, thin skin of a strong fluoropolymer that holds the
glass together if it cracks. The bulbs, which will cost about 拢3 each,
also cut the risk of electrocution, because they make it much harder to touch
the electrodes inside. While the packaging warns against smashing them for fun,
staff at the firm鈥檚 merchant bank, which backed the invention, now use the bulbs
as stress relievers. After a bad day they chuck a few at the walls.
