Instant volcano

On one of the wekend back in shah alam, upon many times request by my nieces and my sons as well, i make an instant volcano. Harith's and Zuhayr's paper mashee volcano back in saigon was a huge succes. They loved them. But it takes weeks to be ready cause paper mashee takes time to dry. So this time using a hard paper, a jar at the center and the special ingredient to make the lava, sodium bicarbonate and vinegar, we made the instant volcano, it takes about 20 minutes to be ready and with enough sodium bikap and vinegar you can play till you dry!.
