SpongeBob poured some of the substance into a test tube and began to heat it. When it started to bubble, he looked into the test tube to see what was happening and pointed it toward Gary so he could see. Gary thought it smelled weird so he took a deep whiff of it. He didn’t think it smelled poisonous and tasted a little bit of the substance. They were worried about running out of time, so they left the test tube and materials on the table and moved to a different station to try another experiment.
