Re: question about silkscreen ink


Date: Fri Mar 02 2001 - 05:49:33 PST

My husband is a silk screen printer, and he has never heard of this kind of
ink. There are screen printing inks you must use a flash cure unit to dry,
but this is when the print is made on material. I know there are air-dry
inks that printers use as well. And there is flourescent ink, which is more
expensive. I would recommend you contact a silk screen ink supplier in your
community and see if they can shed any light on the subject. If anyone would
know about this it would be them.
Oh, and two of the best children's science museums I ever attended were in
St. Louis, Mo. called the Magic House and in Hot Springs, Ark., just outside
of the town. They had large exhibits that allowed you to experiment with a
huge sand box and water. You could create a design by letting a bottle
suspendend on a string, filled with sand,and a tiny hole for the sand to leak
through,be swung and it would make designs on the ground. We came home and
made geo-boards. They had a big one with big rubberbands, but we made some
small ones for our children's classes. Making tessalations is fun and
certainly incorporates science and math skills. They also had a an area
covered with screen and nails of the same size had been dropped into the
screen. You reached under the boxed in area and when you placed your hand
into the nails and pressed lightly (the edges had been dulled so they
wouldn't stick) , a raised design occurred that was visible from the top. It
was neat! We made tornados out of two coke bottles and a little gizmo you
buy to connect the two together. Fill them with water and then turn one
upsidedown and twist it just a bit. Presto, tornado! The best book is 700
Science experiments for everyone, compiled by Unesco. ISBn 0-385-05275-8 or
0-385-06354-7. Our kids made bridges, testing the weight load. Our son won
first prize for an individual project in the Memphis SehlbyCounty Science
Fair when he was in the sixth grade, and all of our children's projects
almost all made it to the finals in the County fair program.. Our youngest
child won a trip to London with Parade Magazine for her project on land
reclamation and ecology. The other book that was a standard then (they are
all in college now or teaching themselves) was the Mr. Wizard's science book.
 Our second daughter who teaches first grade, cuts out the Jax and Beakman
article every Sunday from the funny papers and uses them in her science
center. by placing the article on top and the equipement needed to perform
the project inside in a shoe box. Its very clever and it allows her to
change projects as they study units.

When they were in the fourth grade their teacher, along with parents, would
go on a cool autumn day, out to Shelby Forrest, and the kids would be broken
into small groups with a parent for each group to do a massive scavenger
hunt, after having spend a unit on tress, birds, rocks and weather. I guess
you can tell we like sciene at our house, almost as much as we like art.
Hope these ideas are helpful. By the way, at the Pink Palace in Memphis
there is an area you walk through that is elevated. On each side are curved
pieces of wood that have been planed or smoothed,which mimic the movement of
a bird's feathers in flight! Its reallly neat and give the child or adult
some appreciation of the work a bird must do to stay aflight. Also the Magic
House, had a pair of mechanical arms (like the kind you see in a box outside
of a grocery where you put in a quarter and try to pick up a toy) only they
didn't have the ones with quarters. Theirs were like the robot arms that
they use in Nasa to pick up stuff outside of their rocket. The adults had as
much fun as the kids did going to the Magic House! We havea children's
museum here in Memphis where my youngest daughter works, and they have lots
of things. They have an online web site as well. Also prisms are always fun
to use for refracting light. Hope this is helpful. Wish I was there
helping think things up. This is fun!
