More science experiements!
We went to the science museum again yesterday with Chrysinda and her 5yo son. We went to a chemical demonstration. The lady showed us how to use every day household products for experiments. The main ingredients she used were water, baking soda, dish soap and food coloring.
One experiment also used a balloon. She put baking soda in a balloon, vinegar in a bottle, stretched the balloon to fit the opening of the bottle and then dumped the soda into the vinegar. You can probably guess what happens. :)
Another fun one was with warm water, an Alkaseltzer tablet and a film cannister. She filled the cannister almost half way with warm water and added half the Alkaseltzer tablet. She quickly put the lid on and gave it a quick shake. Try it and see what happens. Warning: stand back a few feet!
From what I can remember, the only other ones she did was mix vinegar and baking soda with nothing covering it, and then she added (new experiment) dish soap to the baking soda before adding vinegar and compared the results. This is also where she used the food coloring. I think you can pretty much use it with anything, just to add color.
Try other mixtures, and even include other household items! We're going to be trying more soon too. This is another great site for some really awesome science experiments! It is where the lava lamp experiment came from. Have fun!

Science experiement
We finally did this experiment I've been wanting to try. We took a 20 ounce bottle and filled it 3/4 full with oil and then to the top with water. We then put some food coloring in, which sank to the bottom just like the water and then mixed with the water. Once the new "lava lamp" was complete, we were ready to make it work!
We broke up an Alkaseltzer (but soon discovered it works better in larger chunks) and dropped it into the bottle. It also sank to the water in the bottom, and then it started making big bubbles and really did look like a lava lamp! It was really cool! I just wish we'd had a big light to put under it to make it look more like a real lava lamp.
The best thing about this one though is that it is non-toxic and the kids got to make it themselves. Jacob loved carrying one of the bottles around (lid screwed on tightly, of course). We also discovered that the lid needs to be loose or off for the Alkaseltzer to work....it needs air!
