Desert science experiment

This week we were looking at Desert habitats so to go along with that on science Wednesday we did an experiment to show how cactus expands when it rains.
Here is what you need......
Folded cardstock (like a fan)
A dish
tape or Staples to hold the card in a tube shape
We put the "cactus" in the dish and poured water in...... We all honestly thought that it would happen quite instantly, that is that it would soak up all the water and probably fall over, or simply would fall over!! (I know, not the most positive thinking.....)

But after about 15 minutes when nothing happened we then added a water "cactus" This soon fell over once the base was wet!

Ummmmmmm, Zeke then decided to ROLL the "cactus" into the water and then stand up again!! And what do you suppose, it WORKED!! From there is slowly opened up and spread out all the folds and STILL WAS STANDING!!!! YAY! YAY! Yippee!!!
It was fun, messy and a good lesson in waiting!!!
