Silicone is just plastic made by polymerizing something like a bulky chemical (styrene).  In English, link lots of tiny rigid particles together to make something stretchy but durable.

length of the rod doesn't matter.\nFind the momentum of the putty.\nThe momentum of the pendulum and putty is the same.\nFind the velocity of the two combined.\nOnce you know their velocity together, find their kinetic energy together.\nTheir potential energy together is the same.\nDetermine how much height they gain.

Wimbley.  I actually wrote The Jim Henson company trying to get the exact fabric to make a banana tree shirt like he had.  Needless to say they weren't real nice to me.

I'm assuming you're asking so you can make some so I posted a recipe for it below. The link below takes you to several other recipies for it.\n\n\nSILLY PUTTY   \n\nElmer's Glue\nLiquid cornstarch (available in a grocery store)\n\nMix equal parts of starch and glue (5 teaspoons of each is generally a good amount to work with). If the mixture is too stiff, add more glue. If the mixture is too runny, add more starch. Wipe off any excess starch and you have silly putty! Try stretching it, pulling it apart sharply, or bouncing it on the floor. CAUTION: It sticks to rugs! (From the "Sticky Business" Room at The Children's Discovery Museum, Acton, MA)

Go to a local hobby craft store, like Michaels or go to Home Depot or maybe Target, and buy STYROFOAM!!!  Shape it out of styrofoam.  Then paint it!  Add putty, paper, and other items onto the foam with glue.
