Does anyone have any ideas on how to recycle these?

wifi blipped again. I use them to store the goods that I buy in bulk at Amish grocers.

Here;s a website that has some ides for crafting with them...mostly snowmen! but maybe it will get your creative juices flowing...https://www.pinterest.com/idarusty/using-plastic-kool-aid-country-time-tang-container/

You can make canisters with them Store you flour,sugar,etc. In them. You could also freeze nuts in them.

Have the kids paint them any colors they want and have them use for storage containers for their items at home. Let them get creative. You didn't say what grade you teach, so it depends on their level. Their names could go on the tops.

Find some really nice DIY tea recipes & make those containers festive for the reason that you are filling with the DIY tea that you've made. Then fill them & tie a little card with jute around the container saying what kind of tea you've prepared.

Kitty / puppy treats

Mix paints in them or store beads.

I would be inclined to paint it (maybe even swirl it in a water/fingernail polish mix) and encourage its use as a nice holder for cotton balls, etc. You could even glue a ribbon around the grove area or apply some other type of bead (think Dollar Store).

I always cut the top few inches off, so that it makes a wide mouth jar. Then they are more usable as storage containers. Just use kitchen shears or heavy duty scissors to cut off top.

Ideas for fabric scraps

We use them for all sorts of things! My daughter stores used (but still good) frying oil in them. I use them to freeze broth and soup stock. We also use them when camping to hold coffee, creamer, and sugar. They also work well when camping as a container for eggs (take them out of the shell first). Most of our uses are food-related, but I also use them to hold small amounts of latex paint when doing small projects our touch-ups.

Classroom or craft room uses I can think of include storing tempera paint, yarn (cut a hole in the lid to feed through), small game pieces, crayons, etc. My daughter suggests using them to hold water for paintbrushes and using the lid to hold paint like a pallet.

Duck tape comes in many great colors and designs. Just a quick strip around the base and you have a nice container. You can label them with a thick sharpy if need be. Maybe, if you have enough, assign one to each child in your class to hold any number of useful things.

I use them in my kitchen to store the remaining portions of food from cardboard containers like small pastas, bread crumbs, cornstarch, rice, tea bags, etc. I don't label the container, sometimes I just rubber band the package label onto the outside. Or I make a label with masking tape, which pulls or washes off when empty. They are just see-through enough that you can tell what is in them.

I save these for my husband' nails, screws, wirenuts (he's an electrician) but also for my daughter's Lego collection because we need to build, take apart and label for future use!!

Attach the caps to the bottom of a shelf, with 2 small screws to keep them from turning, and use them for classroom storage of crayons, erasers, thumb tacks etc. Just unscrew the container from the cap, get the item out or put it in, and screw it back into the cap. Write the item name on the caps with a Sharpie.
