Depending on the size of your kitchen and dining area, along with the number of children there, you might want to consider letting them make their own bath & body products. Glycerin soap is easy and fun. They could also make lip balm, glitter gel, perfume oil, milk bath, bath salts, etc.
Of course, this is easier to do if you're already making these yourself and have the supplies and equipment on hand. Most of these require minimal equipment though, such as mixing bowl, craft sticks to use as mixers, measuring cups or spoons, and of course, something to put it in. Colorants and fragrances for the salts and milk bath can be found at any craft store that sells glycerin soap ingredients and accessories.
For the glycerin soap, you could do the melting, then portion it out to everyone and let them add color and fragrance, and then pour into a mold. Almost anything can be used for molds ... candy molds, tupperware (or similar), plastic containers (like for yogurt, margarine, etc), plastic cups, and more. I rarely make glycerin soap anymore, but I still look at things and wonder if I can use them as molds whenever I'm in stores.
