Egg Crystals - Cont.

posted Mar 8, 2011, 10:33 AM by K Day

On day 2 we discovered that the best results came from Salt, Vinegar and Baking Soda. The green egg is Vinegar and the Orange Egg is our Baking Soda. As you can see the crystals grew through the shells, not just around the edges. 

Finally after most of the liquid had dried up we were left with both soft and hard crystal formations. Taka' scraped some crystals off, observed them under the microscope and recorded his findings in his Science journal. He thought the Vinegar crystals looked like rocks (more smooth than jagged), the salt crystals looked bubbley and the Baking Soda crystals was jagged. Taka had so much fun he wants to do it again, with different ingredients :)
