As part of the spring book fair, Lucy got a book called “Monster Science”, and we’ve started working our way through it beginning with mummifying an apple.
“Today – produce. Tomorrow, THE WORLD! Muhahahahahaha!!”
We started by cutting the apply into two groups:
One that would be mummified over the period of a week:
And one that would be our control, and just sit out:
Next, Lucy prepared a mixture of salt, baking powder, and the “mummifying powder”* from our kit:
Which she then poured over the chunks of apple in the beaker:
Next, we boxed up both containers of apples, taped it shut, and found the darkest part of our basement to keep them in for the week:
That was last week Sunday. Today, we unboxed them:
As you can see in this shot, the control apples are quite recognizable. The peel is still red, and the meat is still crunchy. The mummified apples, though, turned a dark brown, and the meat felt more like a sponge than an apple:
CJ commented that we should have cut both sets of apples up into the same size pieces, and then we could have compared the relative sizes. That was a great idea, and we could have answered the question of “did the mummified apples shrink, get bigger, or stay the same?” Oh well. Next time, Igor.
* UPDATE 5/23/2017: I looked on the box, and they listed the contents of the “mummifying powder” – crosslinked acrylic acid and sodium acrylite copoloymer.
