As I walked out of the store, another salesperson called out and told us to leave the mattress to expand for at least 24 hours, before use. I think they must use a powerful vacuum when they pack them at the factory. It was only a couple of cm thick when I rolled it out. It has been left for 6 hours now and is just starting to look like the one on display in the shop.

At one time, it was common to use spider silk as a thread for crosshairs in optical instruments such as telescopes, microscopes and telescopic rifle sights.

when the battery place says they will deliver my new AUX battery today, they really mean tomorrow. lol

Saw a doco on TV about an old Brit collecting spider web early in the morning when it was covered in dew. He undid the web rolling it up for use in rifle scopes.

Do they still use it today?

I don't think so.

In extraordinary scenes filmed for a new documentary, young dolphins were seen carefully manipulating a certain kind of puffer fish which, if provoked, releases a nerve toxin.

Though large doses of the toxin can be deadly, in small amounts it is known to produce a narcotic effect, and the dolphins appeared to have worked out how to make the fish release just the right amount.

Carefully chewing on the puffer and passing it between one another, the marine mammals then enter what seems to be a trance-like state.
