Re-dyeing faded clothes can bring new life to them. You can dye them with the original color or overdye them for interesting color effects. If they're cotton, all you need is procion mx dye (costs around $5-7 per jar on amazon) soda ash/washing soda, something to stir with (I use paint mixing sticks) and a clean plastic bucket. Non iodized salt is a good addition to help the fabric soak up more of the dye, but not strictly necessary. Wear rubber gloves the whole time you're handling any of this stuff, soda ash is caustic and dye will stain your hands obvi.
Animal fibers and nylon can be dyed with food coloring and an acid to set the dye. Typically vinegar, but citric acid works too (unsweetened kool-aid packets).
Add the food coloring to water first, make sure it's dissolved well if using icing pastes, add a big splash of vinegar, add the fabric, boil until water is clear. Or mostly clear, the fabric might not take up all the color. Rinse throughly! If color runs in the rinse water boil it in more vinegar water.
Because food coloring is food safe you can use the pots you cook in for this.
May not work on silk, but wool/alpaca/mohair/other animal fibers work really well. This is probably not useful to most people, wool garments aren't ubiquitous anymore and run on the expensive side, but just in case you should know this.
If you knit finding ugly wool sweaters at thrift stores can be a way to get nice yarn for cheap. If the seams are surged then it's no good for recycling, the yarn will unravel into multiple short pieces.
3) Rice. Omfg anything over rice makes a decent meal. Learn to cook it right though. No need to eat mush.
If you have a microwave and a casserole dish you can make perfect rice in less than twenty minutes.
1 cup rice, 2 cups water. Microwave on high for about ten minutes.
2 cups rice, 3 cups water. Microwave on high for about 15 minutes.
If you're unsure about the time try cooking for half the time. If the rice is not fully translucent cook for a few more minutes. If you think the rice might be too dry add some more water. The times and amounts above work for me.
When the time is up if the rice is fully translucent but seems wet, cook for another couple minutes. Repeat that until the water is absorbed. Make a note of the time and the amount of water you used for next time.
Might take a couple tries to get it right but it's foolproof when you do. This works on every variety of white rice I've ever used. It does not work on brown rice.
