By the end of chapter 4 mark has created a problem for himself. Explain the situation

By the end of Chapter 4, Mark has managed to create a problem for himself in the following way:

Mark, a brilliant yet impulsive young scientist, is determined to find a way to make himself invisible using his scientific knowledge. Despite multiple failures, he continues to experiment with dangerous chemicals in his basement laboratory located in his family's Victorian house. In an attempt to finally achieve success, he concocts a new formula that he believes will make him invisible.

Excited about his discovery, Mark eagerly injects himself with the experimental serum without considering the consequences thoroughly. At first, everything appears to be going well as he starts to feel a strange tingling sensation before disappearing entirely. However, he soon realizes that being invisible is not as glamorous as he had imagined.

Mark quickly discovers that his invisibility can only be controlled for short periods of time and comes with unexpected side effects. Throughout chapter 4, Mark struggles with the repercussions of his reckless actions. He realizes that being invisible makes it almost impossible to interact with others or navigate through the world safely.

As Mark grapples with his newfound invisibility, he realizes that he has inadvertently distanced himself from his friends and family. He is no longer able to attend school or participate in his usual activities without attracting attention. Moreover, he starts to notice that prolonged periods of invisibility are taking a toll on his physical and mental health, causing him to feel exhausted and disoriented.

Frustrated and desperate to find a solution, Mark becomes increasingly isolated and overwhelmed. The problem he has created for himself is that his desire for invisibility has left him trapped in a state of invisibility that he cannot control, causing him to face significant challenges and hardships. Mark must now face the consequences of his impulsive actions and find a way to rectify the situation before it spirals further out of control.
