We spent the end of the day transforming our "work" area into a "Laboratory." I don't know who had more fun: the kids who were watching the video Young Frankenstein (a couple of the kids were doing awesome imitations of the monster noises and then laughing and laughing; another kept activating step-by-step that had various screams recorded on it; it was all too funny!) or the adults who were playing with a variety of solutions and mixtures and concoctions to create the lab (more on that later). The cabinets and table are covered in white shower curtain liners left over from our sensory room make over.
Here is the "Nevermore" raven I found at Party City keeping watch over the tray of monster parts for the sensory story. Below are a bunch of sensory bottles (more info below) and other creepy lab experiments including Alien Slime (awesome stuff! It's even scented!) and a variety of test tubes and beakers (really intended for sand art but for the price they were perfect for us).
Another view of our "experiments" including the Mad Lab Kit, and a color changing brain and heart. I picked up the electo-static ball years ago at Wal-Mart. I stuck one of our other "mood" lights up there too, just to add to the effect.
The large flask has green tinted water with ping pong eyeballs. The flask on top of the "burner" has purple tinted water with dish soap suds.
I got the idea for the sensory bottles from http://www.kinderfriends.com/discoverybottles.html and then went my own direction. They are concoctions of various combinations of water, Karo syrup, baby oil, dish soap, and hair gel (the orange ones) with food coloring, glitter, confetti, and small objects added in (the orange bottle in front has hair gel and rubber eye balls). One or two just have loose beads inside so they rattle. We used the same technique to fill most of the flasks, beakers, and test tubes. They turn out really cool and the kids have fun manipulating them and watching what happens when you turn them over. I used Gorilla Glue to secure the lids to the tops of the bottles for safety. I left the flasks and test tubes open so we could recycle them but the kids won't get to play with most of those.
