O Vulcão De Eda
A 1978 Eda eruption broke the island of Tanabas in Dingabulu.It caused great damage.The stones broke,and lava came out.CO2 came out of the lava chamber,and it erupted again.That time we had stones braking,lava flows,CO2 coming out,and powerful eruptions.
This is the chemical equation for the reaction of bicarbonate of soda with vinegar:

Dear Stroofie Uno,
Tell your mummy sorry I haven't written for so long - I am a very bad friend who needs to be kept in line by Tommy.
I really like your blog. It sounds like volcanos are your new thing. I have two volcano stories:
(1) when I was four I made a volcano out of plasticine and tomato sauce. I moulded the sha[pe of a mountain and then poured sauce in and covered it up. Then I made everyone watch and I squeezed the bottom of the mountain to try to make it erupt. It didn't work so I squeezed really hard and then all the tomato sauce came flying out at once and splattered me and my sister in the face (she was really angry!).
(2) When I was in Italy when I met you guys I went down to Silicy and climbed Mt Etna. It was amazing. It took us all day to climb and we were completely black by the top from all the ash. Our feet would sink so deep into it. The most amazing thing that we found was a little corner where there was ice. We couldn't understand how there could be ice on top of an active volcano. Maybe you know from your science lessons how that could happen and you can explain to me. When we got back to the bottom we went back to the place we were staying and tryed to wash ourselves and our clothes - but heaps of it just wouldn't come off. Everytime I took off my sneakers for the next couple of weeks, my feet would be black with Etna ash. We called it the 'Etna Foot Disease' and pretended that it was contagious and meant your feet were going to fall off at any minute.
Hope you are well and happy. I ate sooooooo much chocolate over Easter. Please give kisses to your mum and dad from me.
Love Roofie Stroofie
