I am adding detail to my writing to make it more interesting

The problem is that it is too noisy in room 1, so we made ear phones. We learnt about the sound, first by banging on the metal soccer post and the blue brick wall. We heard sound waves and vibrations.  Then we learnt about what blocked the sound the most. The materiel we used was cardboard , foam, rubber, tissue  beans and a  cup. So rubber blocked the most sound. So we made Ear muffs. I used cardboard rubber and tape. It looks like bunny rabbits ears.
