I am told that the formula for large, strong bubble membranes is 1 cup Dawn to 10 cups water, plus three tablespoons glycerine.  But the cool, sciencey part is dipping 3D frameworks into it:

Following up on the "baking soda + vinegar reactions" - combine that with a pH indicator and try to produce a relatively pure solution of sodium acetate. Then use that solution to demonstrate supercooling.

Mix some ammonia into a solution of magnesium sulfate (epsom salts). It will produce a white precipitate of magnesium hydroxide. Filter that out and use it other acid-base reactions.

Shine a laser pointer at an angle onto a compact disc.

Start a collection of elements from the periodic table (preferably in pure form, but accepting compounds for some of the more difficult ones like fluorine). You can make your own hydrogen, oxygen, and chlorine through electrolysis.

Borrow a telescope or a pair of binoculars and look at the moon and whichever planets you can find.

Extract DNA from fruit.

Check out the Make magazine blog and Hackaday for awesome stuff to do.
Off the top of my head-
vibrating brush bots
sugar rockets
jello magnifying glass
Take apart broken stuff (old printers, VCRs, DVD players, anything mechanical) and build new stuff from the parts
Arduino projects

Also consider getting your kid involved with First Robotics. I got involved a few years ago as a mentor and it's awesome.
Buy your kid the Mad Scientist's Club books. They made me the geek I am today.
Make it fun- if it blows up, fizzes over, makes cool noises, moves around, glows, changes color or otherwise does something cool, kids will be engaged.
Have fun and be careful.

Confabulat: Go outside and show them a tree.

We did that. followed a creek to see where it went.

Also so far we did
mixing food colors in beakers to wee what colors we can make
baking soda and vinegar reactions
elephant toothpaste
bought and worked a basic electricity kit
iodine clock
measuring acids and base pH (not really a hit)
chromatography with sharpies and waterbased markers using water and acetone

And i am about out of ideas.


the_rev: Show them how to start a fire with the sun and a magnifying glass. Then shown them it can also be done with a concave mirror.

I like this one.  need to get some dark glasses to protect the eyes...thanks.
