Making it rain by holding the hose sprayer in just the right position makes great rainbows, or if you prefer you may call it separating colors by refracting the light.
Recipe for butter nut squash
Cut some fresh yellow squash into chunks
Cut some fresh onions into chunks (depending on how much squash you use, one onion should do it)
Cut some fresh tomatoes into chunks (one or two tomatoes should do it, again, depending)
Layer the squash, onions and tomatoes in a casserole dish and add crumbled or chunked feta cheese
Finally, generously dot the top of your layers with pats of butter (or spoon out of the tub, depending on whether you get stick or a tub of butter), salt and pepper depending upon whether you use salt and pepper.
Bake on 350 until the squash is tender.
