Beakman and Jack's Bubble Book
More than a book, it's an activity kit. Includes a square bubble frame that you
can use to create SQUARE BUBBLES!!! "Impossible," you say? They say
it can be done. The book shows how soap film shrinks using rubber bands and twisted
coat hangers and much more. Put your hand inside a bubble. Watch a tiny speck
of dust pop a bubble. Paint a rainbow picture. Create an enormous bubble maker
and form recycled bubbles from soda-pop rings. Lots of fun in an area that has not
been previously explored in a science kit. CURRENTLY UNAVAILABLE
Water Clock
Recreate an ancient Roman water clock. Explore the physical properties of early

spanned much of the known world. No. SF290-WC. Only $29.95
When does a solid take on the properties of a fluid?
We maintain that these Pin Art Modules do just that. Each pin is housed in its own
shaft that keeps it perfectly aligned. By placing the module over an object, the
pins are pushed upward the same distance as the objects depth. Thus the face of the
pin has a fluid property. Besides, we couldn't figure out how else to classify these
things. Great fun and entertainment, but can also be used to form patterns for craft
projects and model making and other hobbies. Round Pin Art Module. 5" diameter. No. SF290-PR. Only $12.95 Rectangular Pin Art Module 4" x 5" No. SF290-PS. Only $12.95
