Faceted beads scoop well with the LEGO front-end loader, back hoe, and
Technic seat.  The 8mm size works better than the 6mm size.

LEGO Shop at Home (telephone 1-800-453-4652 anytime) sells the front-end and
backhoe scoops in Service Pack #5284 for $4.50.  Many other sets have
similar scoops.

You may find faceted beads in stores among "crafts", usually in larger
discount department stores or specialty craft stores.  You may find some at
internet web sites, too.  Prices:  6mm x 850 beads / 230ml $3; 8mm x 1300
beads / 600ml $5.

Description:  plastic, transparent, colored, polyhedron shape, each bead has
34 regular faces in 3 different shapes, hole through center (because most
typicaly buyers string them).

Scooping bulk:   Both sizes of beads scooped easily from a bin filled at
least 2cm deep with beads.

Scooping sparsely:  Scooping a single layer of beads proved more difficult.
The scoop must herd the single layer to a smooth vertical surface then
simultaneously slide up the surface while tilting back to let the beads drop
back into the scoop. The size and spacing of the teeth on the front-end and
backhoe scoops proved too large to capture all 6mm beads but managed to
capture all 8mm beads by lifting them up against the vertical surface while
slowly tilting back to let them drop into the bucket. The flat blade of the
Technic seat lifted both sizes against the vertical surface for successful
scooping.

Scooping surfaces:  Smooth, flat surfaces allowed more complete herding and
scooping.  Bins made of LEGO bricks can have smooth walls adjacent to smooth
floors if built with angular techniques, e.g., connecting Technic studded
beams (with holes) at right angles with pegs before building up the brick
layers for each interior face of the bin.  The backs of base plates proved
adequate for 8mm beads but the little dimples sometimes caught the 6mm beads.

Bouncing and rolling on smooth hard surface:  The larger 8mm beads rolled
and bounced less than the 6mm beads.  When pushed along at the speed
10cm/sec and released for free horizontal roll, the 8mm beads continued to
roll 1 - 4 cm (average 2cm).  When dropped from a height of 5cm, the 8mm
beads bounced away 7 - 16 cm (average 9cm) horizontally.  The 6mm bead
rolled more after a similar push and bounced farther away after a similar drop.

Sorting machine:  Do you think that you could build a sorting machine with
only LEGO parts that could separate the beads by size from a mixed batch of
beads?

if you have no use for them afterwards).
If dice are too big or you just don't like them: Do you know those "chips"
they use with parcels. They are not to big (what dimensions do you think of?
As small as 1x1bricks?), they are light and they do not make a mess.....

What media works well for scooping with front-end buckets and back-hoes,
e.g., the scoops in Service Pack 5284 "Loading Grabs" and set 8459
"Pneumatic Front-End Loader"?

We need a medium that scoops easily from a flat surface, a pile, or a bin.
It should not roll away when touched by the scoop.  It should not make a
mess like sand or mud.

Rokenbok balls roll too much.  The flat sides of 1x1 bricks do not afford
easy scooping.  Short K'Nex pegs scoop well because they have rounded • edges,
but they roll, too.  Has anyone tried the guts of Beanie Babies, i.e., the
plastic beads?
