Poly Density Bottle
# 2B40.711

Initially, the alchol is on the top and the saltwater is on the bottom.

Immediately after shaking, the alcohol and the saltwater are mixed in the middle

The alcohol and saltwater begin to separate
Description: The bottle includes 4 substances with densities in the following order (from small to large): alcohol, white beads, blue beads, saltwater.

Instructions: Shake the bottle vigorously and the white beads will settle to the top and the blue beads will settle to the bottom (see the second picture above). The reason for this is that the alcohol and saltwater will mix, and the mixture's density is between that of the two beads. After several minutes, the alcohol and the saltwater will separate so that the beads order from top to bottom is again: alcohol, white beads, blue beads, saltwater.

Parts: Bottle filled with 4 substances

Purchased/Built: built
