35 lb tungsten "ballast" blocks (race cars): $1877

Twice as dense as steel& 50% more than lead, but what a price to pay
for the little space that it saves.

We've got a block of tungsten that pretty much fills up the inside of
a little plastic Pelican case. It's funny watching people do a
double-take when they pick it up.

What's it for?

Testing a gravitational sensing instrument, so something close to a
point mass is useful.

What..couldnt get a good deal on a micro blackhole? Check Edmonds
Scientific, I think they are running a special this week.

Those damned things evaporate too fast.

Besides, when you pull your hole shot, the ballast would stay where it
was when the car took off! Bummer if it was right in front of the
driver.
