Volcanoes

Over the past three weeks, we have constructed and painted volcanoes, as well as make them erupt! 

Firstly we created our volcanoes by wrapping newspaper around plastic bottles to form a conical shape.



Next we papier-mâchéd our volcanoes in preparation for painting it. 


Next we painted our volcanoes!




Finally we made our volcanoes erupt!! Firstly we put some washing up liquid and baking soda (bicarbonate of soda) into the bottle. To create the reaction, we mixed in some vinegar. See what happened below!
