My groups brick

We made bricks a couple of weeks ago and it was so much fun!
Mr. beiers(my teacher)put out a few things that we could put in our super brick like plasta of paris,cement and clay.
And we (which is my group the dorks) added a few extra things to our brick like rubber dust, and pencil shavings.
Now anough chata-chat lets get on to some facts.

1. How can a plasta brick get stronger? it will only get stronger if you put in yhe right ingredents.
To be honest i dont know how to make your brick stronger.

2. what is to be tested? the brick of course.

3. how is it going to be tested?by stepping on it or using a bulldoser(there are many other things you can do)
