fire works in the jar

Hello now we are going to explain our experiment fireworks in the jar.

Naroa told us that we were going to put in groups and each group was going to make an experiment. The names of the experiments are : fireworks in the jar,the cd rainbow, the sugar rainbow and color changing the milk.Then we wrote these steps:
                             1 watch half of the video

                             2 write the hypothesis

                             3 the material of the experiment
                             4 decide who brings what material

                             5 see if our hypothesis is correct
                             6 our hypothesis is not correct

The problems that we had with the experiment are:

We didn'tcalculate the quantity of the water ,we threw very big drops and we threw a lot of oil.

We like the experiment because we play and laugh..

Here you are the video of the experiment.
