Who missed the TV special?
M:Did you watch the TV special about barnacles last night?
W: No,I missed it. What did you learn about them?
M: That they glue themselves to rocks in the ocean,shortly after birth. They also stay in the same place forever.
W: Right,have you ever tried removing one of these things? It would be easier to chip the rock away than to get the barnacles off.
M:Exactly,and that’s why scientists are trying to figure out what the barnacles glue is made of. It’s considered one of the strongest adhesives in nature.
W: And it would have the advantage of being able to work on wet surfaces too.
M:Precisely,and because it’s natural protein,it probably wouldn’t be harmful to people like so many synthetic glues in use today.
W: Think of all the ways doctors and dentists could use such a glue,mending broken bones, washing false teeth.
M:There could be countless uses. Scientists hope to learn soon exactly how the glue is made, so that people can make use of it.
