You can then paint the sculpture using water base paints.

To better preserve your art work, after the paint is thoroughly dry, brush on clear nail polish to give it a shiny finish.

EXPERIMENT.

Acid indicator Chemists use "indicators" to test whether

a substance is an acid or a base.

Indicators work by turning a distinctive color when added to an acid or base. You can make your own indicator from red cabbage. You can also make indicators from the juice of elderberries or blackberries.

1

To make your indicator, take a good red cabbage — it must be red cabbage

— and chop it up finely on a chopping

board. Then boil about a pint of distilled

water in a saucepan.

You Will Need

You can use cups with holes punched in the end to blow large bubbles. To get large bubbles, thread three feet of cotton string through 2 straws and

tie the two ends of the string together.

Separate the straws to form a rectangle shape of string-straw-string-straw.

Put your soap solution in a large container like a baking dish. Dunk your string-straw into the
