My experiment for science class this unit was about bonding metals and acids to make salts. We did this by placing our metals in a container with our salts and let that react for 1 minute to 1 day depending on the metal. Then we poured the liquid into another container like the one shown above and we heated up the liquid so it then turned into salt. This is not as easy as it seems though. For example, if you pour the liquid into the container to heat it and it still has some acid in it, you failed. If you heat up the glass to an extent where it cracks, you failed. All in all, I think this experiment was really fun.
