Hyperactive kids, could this be the cause? This demonstration will open your eyes to the amount of energy stored in these little candies.
What you do is melt a small quantity of potassium chlorate in a large test tube clamped to a ring stand. Use long-handled tongs to introduce a Gummi Bear candy to the test tube. The sugar in the candy reacts vigorously with the potassium chlorate, causing the bear to 'dance' amidst bright purple flames.
