Gravity Busting Car: Can a 2000 pound car hanging from a crane defy gravity when it's dropped? #

When a fully exteded Slinky is dropped from a height, it seems that the bottom of the Slinky momentarily lingers in mid-air before the entire thing falls to the ground.

Based on this gravity-defying "hover effect", Adam challenges the MBJrs to study this phenomenon with all kinds of elastic materials and objects, eventually working their way up to achieve the same effect with a 2000 pound car!

35 Mile / 45,000 Word Pencil: A standard no. 2 pencil can draw a 35 mile long line and write up to 45,000 words — write or wrong? #

The pen may be mightier than the sword, but there’s nothing like a good old-fashioned pencil to get the lead out. (Technically, pencil lead is a combination of graphite and clay — that's a longstanding myth.)

But busting myths is what this show is all about, and another pencil-related parable is that a regular no. 2 pencil holds enough graphite to draw a line about 35 miles long (or to write roughly 45,000 words). Could this be true? Adam and the MBJrs are ready to find out!
