Recipe
IMPORTANT: You will need one sober adult with a sense of scientific wonder to be present....
The items you will need to carry out this experiment are: white vinegar, bicarbonate of soda, a tightly sealable sandwich bag, a table spoon, some kitchen roll, some goggles to protect your eyes and a bath or sink to prevent the mixture exploding everywhere.
1. Pour around 100ml of white vinegar into your sandwich bag
2. Place two table spoons of bicarbonate soda on to a sheet of kitchen roll
3. Fold the kitchen roll into a parcel
4. Drop your parcel into the vinegar and tightly seal your sandwich bag
5. Give the bag a good shake
6. It should then rapidly expand and EXPLODE!
