-noodles (any kind you can thread through)
This list seems long but it's likely a lot of things you already have.
The directions I found for dying noodles was a capful of rubbing alcohol and 5 drops of food coloring in a baggie then add in about 10 noodles at a time for the best color. Having never done this before I followed directions. After I had the first batch of noodles in I realized this wasn't going to be very clean or efficient. You can't just dump the noodles because there's still a lot of liquid left in the baggie. So, I found myself a glove to pull them out. The next issue was getting more noodles in the bag...you have to hold the baggie open, still have a glove with food coloring on it and are trying not to spill/stain anything. I gave up and just poured more alcohol and random amounts of food coloring in and filled the bag with noodles. It worked just fine. You need to manipulate the noodles around for a little bit to make sure they are all getting wet but I thought the color turned out just the same as it was only doing a few at a time. I would also recommend using freezer bags as the noodles punctured holes as I swished them around in just a little sandwich baggie. I will say though that mixing colors to make more fun colors didn't work. The orange turned out the same as red and the teal turned out the same as blue. It must have something to do with the color of the noodle because it looked like the right color in the baggie. The tutorial I read also said they had a hard time getting purple, it always turned out black.
You can probably use a variety of items as your 'thread' but if you use yarn you need to wrap tape around the end because it starts to fray right away. I just had yarn on hand so that's what I wanted to use.
Some of them liked throwing the noodles more than threading them! It was a good sensory bowl too I guess.
Some of the younger ones just made a necklace but JP enjoys threading so we made wind chime. I punched 4 holes in a paper cut to go around.
For the hook I used a pipe cleaner. I folded it in half and twisted the bottom and poked it through a hole in the top. I then spread out the tips of the pipe cleaner kind of like a drywall anchor.
