A chemistry experiment in a lab with a flask of glowing blue liquid reacting and emitting smoke, lit by orange and blue light.

In the original experiment, 4g of CaCO3 was weighed out in a weight boat on a scale. 20mL of 1 M HCl was also measured out into a measuring cylinder . The HCl was poured into a beaker, the temperature was recorded and then the CaCO3 followed. From the time the CaCO3 hit the HCl, the mass was recorded in 15 second intervals. Once the reaction ended, the final temperature was recorded. See more
