Table 2

The average initial mass and water absorbed for each sand sample. Numbers in parenthesis are standard deviations of measurements.

Sand sample	Water mass (g)	Total mass (g)	Water-to-sand ratio
Sample A	37.0 (1.5)	350.7 (11.6)	11.8%
Sample B	15.4 (1.1)	336.1 (9.0)	4.8%
Sample C	15.8 (0.8)	392.1 (8.4)	4.2%
