Asked by Zhuna87 1 year ago



borax, boric acid, flux

Does anybody know the relationship of borax and boric acid? Are they different forms of the same thing? Are they related at all? What if any do these have in relationships to flux to silver smithing. (I think the flux is Boric Acid but I am not sure.) I have a box of Borax, that I use to make liquid laundry soap. - I also used it to make crystal snow flakes - beautiful. Just curous.

Ant Killer!

It seems every year we get ants in our kitchen. I don't know if its a seasonal thing or just coincidence.This time, however, we were able to effectively combat them with a home remedy. We mixed boric acid & sugar in water and set the concoction in a few little lids across the kitchen. We used roughly a 1:1:1 ratio, but it isn't an exact science. It's also not important if it doesn't dissolve completely.The idea behind this is that the boric acid will not kill the ants instentaneously. In fact, the sugar will lure ants to it. Also, this amount of boric acid isn't harmful, even to most pets. I don't have any pictures to do an instructable, so I thought I'd share it here. If someone else does this, feel free to do an instructable. (no credit needed)

Make socks which pause your TV show if you fall asleep

Sometimes I fall asleep when I'm watching TV and don't realize it, because I dream the rest of the story. Then of course when I wake up I'm thoroughly confused: why are the bad guys still alive? They had transformed into evil giant ants then I saved the day by feeding them peanut butter laced with boric acid! When I finally realize I'm not the hero in the story, I have to either go to bed and abandon all hope of finding out what really happened, or watch the story backwards, sped up and silent till I see a scene I recognize. No fun! These socks will protect the integrity of your show's story line: build them by following this tutorial, wear them while watching TV and they will pause the show when you fall asleep. Of course they won't keep you from dreaming up an alternate ending, but at least when you wake up you can start where you dosed off and find out who the murderer really is. This is a Netflix tutorial, and it's supposed to pause Netflix shows... but I'm sure it can be adapted to turn off Amazon Prime or other streaming services...
