silly putty isn't green

My friend's nephew left his 'not' silly putty in his car. To paraphrase a nine year old, "It's not silly putty, because silly putty is pink, not green. I mean everyone knows that." I don't really dig on kids all that much, but that cracked me up.
Even though we're in our thirties, silly putty is still fun. One morning it entertained us over coffee for a good hour. Then we started to ask questions like could the silly putty seep through the holes in a salt shaker? How far could gravity pull silly putty? We decided to test it out.
We knew the chances of the putty going through the holes in a salt shaker was a lofty aspiration. A potato masher on the other hand had much larger holes - it was perfect. It wasn't even a question of whether it would go through, but how long it would take. It seemed like cheating to start out with flat 'not' silly putty, so we rolled it into a ball first.
As you can see here the holes are pretty large. We had to fashion a support for the masher, we used a jar and an old towel - you know, your standard scientific equipment. All we had to do now was wait for our friend gravity to do it's thing.


It started to flatten out right away - yippee - this was totally going to work. We got ready to go to the beach. An hour later, not much more progress. We decided to head for the beach and figured we'd come home to an oozy silly putty mess.

Nope. You can see that it oozed through the holes a little, all in all it was an unsatisfactory result. But, for the effort invested I guess it was still a fun science experiment with 'not' silly putty.

UPDATE: In response to Keith's comment, we left the silly putty on the masher for about 12 hours. I think microwaving it might be cheating, but am willing to give it another go starting with a flat patty instead of a round ball. There might be more seepage that way.

How long did you leave the not silly putty on the masher?

Have you tried microwaving it? Be careful you may disrupt the space time continuum...
