Silly Putty is a plastic "clay", marketed as a toy for children by Binney & Smith Inc. Silly Putty comes in classic, glow-in-the-dark, glitter, and four hotfluorescent colors. Silly putty is a fun toy that many children have played with before – but most do not know the science behind it. Silly putty is a colloid.
Silly Putty is a pretty unique substance. It stretches without breaking, yet it can be "snapped off" cleanly. It bounces higher than a rubber ball. A chemical compound made of silicone oil and boric acid, Silly Putty is composed of flexible molecules that give the material flow. The silly putty is formed by joining the globules using sodium borate (a cross-linker).
Earlier this year, an announcement came across the news wires that Silly Putty is celebrating its 50th year. More than 300 million Silly Putty eggs (4,500 tons) have been sold.

Mix together well. Set on trays for play, or use waxed paper. Can be used as the commercial Silly Putty is. Store in an airtight container.
Silly putty is made of long flexible molecules all tangled up. If you just let the putty sit or smoosh it with your fingers, the molecules slide over each other and the material flows. When you drop it, the impact tries to make the molecules move past each other very fast. They can't do this, they're too tangled, so instead the molecules deform, like stretched and compressed slinkies. Then after the ball stops, they rebound to where they were, and this generates the force that causes the ball to bounce up. Jello is also made of long flexible molecules tangled up (with a lot of water in between), but in this case they're also attached to one another, so they can't move past each other at all. So Jello won't flow no matter how slowly you moosh it. All that happens eventually is that the molecules or the junctions break, or more complicatedly, the network slips along a fault, and the Jello rips or crumbles.
The first step is spray WD-40 on the mess. The WD-40 will remove the Silly Putty. The next step is to TRY to remove the WD-40 with rubbing alcohol. The final step is to clean the area with soap and water.
You should always do a test spot on fabric or carpets with the WD-40 procedure first.
