A Fabumouse School Adventure by Geronimo Stilton

Luckily, Professor Sandsnout put the cat mummy and all those bones back into the sarcophagus. .His talk was over. I sighed with relief. Now I could listen to the next mouse, Professor Miles Magmamouse. Professor Magmamouse lowered the shades and put on a video that explained everything any mouse would want to know about volcanoes, volcanic eruptions, and earthquakes.
WHAT AN EXITING LINE OF WORK!
He had seen hundreds of volcanoes and lots of lava in his life.
Suddenly, my job seemed wimpy and BORING.
At some point, Professor Magmamouse asked me to give him a hand with the EXPERIMENT. I listen closely as I didn't want to mess up. I had to look good for Benjamin!
" Geronimo, when I say NOW, put three drops of vinegar into the mouth of the volcano, " Professor Magmamouse told me. "It is important you only put three drops, is that clear?"
At that moment, my nose began to itch. I tried to hold my breath but I couldn't stop myself from sneezing.
"AAAAchoo!"
And that's how I poured the entire bottle of vinegar into the volcano. It erupted, and lava oozed everywhere!!
