More experiments. Hannah, Ria, Vyal, Shraddha and Mariam

Hannah made elephants tooth paste. Her mixture of water, dishwashing liquid, bleach and bicarb really caused and amazing reaction. A gush of bubbly liquid came gushing out of her bottle!

   

   

  

Ria showed us how to inflate a balloon using bicarb and vinegar. The gaseous reaction it caused made the balloon inflate very quickly.

     

    

    



Detective Vyal told us all about the three different types of finger prints there are - arches, loops and whorls. We all had our finger prints taken so that we could see which type we had. After that he demonstrated how the police pick up fingerprints at a crime scene. It was most interesting.
