Last week we made the volcano from the Magic School Bus monthly science kit. If you read my earlier review of the MSB science kits, you know I have mixed opinions about it.. However, this experiment actually worked really well! We were all impressed.
First we paper mached (equal parts flour and water) a water bottle covered in black construction paper.
Then we painted it black.
We added dishwashing soap (provided in kit), baking soda, food coloring (I only had a little green on hand--next time I'll get red or orange for more realistic lava), and lastly the vinegar.
Stand back and watch it erupt!
