Good afternoon, having a cold wet day here, started raining while I was waiting for Leo's driver to arrive.
It is indestructible stuff day and today's stuff is natural glue.
Humans use a lot of glue, it's good for mending stuff but we are just amateurs as our glue is nothing like as good as the natural super glue that some living things make.
Most animals move around but a few such barnacles and muscles stick to a surface and stay there. To do this they make a small amount of super strong glue to attach themselves to rocks, boats and walls.
Not only is it incredibly strong it is also waterproof and strong enough hold fast and passing feet.
Some of the strongest natural glues are made of water bacteria, which uses them to stick to surfaces in fast flowing water. Scientist have also found that asparagus beetles make mind-boggling strong glue to stick their eggs firmly onto asparagus plants.
Scientists are now copying the chemicals found in these natural glues and combining them to make the ultimate waterproof glue. It could be used to mend ships underwater. SSS
