Somewhat related household tip: When something wooden cracks or breaks and needs gluing, but you don't have any wood glue at home, you don't need to buy any. Just dissolve a sheet of gelatine (which you do have, no? :) in a bit of water and warm that in a water bath for five minutes. Use a brush to apply some of that to both glue sides and press it firmly together. As an added bonus, these glue joints become soft at ~50-60 °C, so can be fixed up later again. Structurally, it's pretty much as strong as any wood glue.

That's basically hide glue, isn't it?

Hide glues are great in low-humidity environments but can loosen in high humidity. They're useful for fixing musical instruments, for example, because hide glue joints are reversible and repairable. Hide glued joints will release easily with the application of heat and steam. I was surprised to find that most older musical instruments have been repaired to a greater/lesser degree thanks to the use of hide glue. Bow makers (as in "bows and arrows") commonly used hide glues in regions of low humidity, but a Turkish bow composed of tendon, bone, sinew, wood, horn and hide glue likely will fail to function properly in a rainy-weather locale.

For some use cases, you can use rice. All you need is some leftover (cooked) white rice and a bit of water. Turn the thing into a paste of the desired consistency, and voila, a basic glue.
