Sugar Cube Science, Keep the Damp Out, Thursday, 6th March, 2008
We poured water on a sponge. The sponge only soaked up water when it was already wet.
We tried newspaper too. It soaked up a little water but not much. 
We made a sugar cube tower and put it in water with green dye (for St. Patrick’s Day). All the sugar cubes sucked up the green water.
Our experiment didn’t work too well. We found that the sugar cubes dissolved faster than they could absorb the coloured water through any material but paper towels.

Next we made towers with one cube on the bottom, then another layer of something to test, then 2 more sugar cubes.
We tried sponge, paper towel, newspaper, tin foil, cardboard, card, cling film and plastic in between the cubes of each tower.

When the sugar cubes dissolved, the whole tower fell over and the cube on the top absorbed the coloured water as soon as it touched the water. It was very interesting and fun anyway.
