Okay, I need to write an article about how to make Oobleck. Let me start by understanding what the user wants. The keyword is "How To Make Obobbleck," so the article should be focused on that. The user provided some context points: "What is," a link to full instructions, "Galaxy," the title from the project, "Learn" mentions, and a reference to Jessi's lab. First, I should define what Oobleck is. I remember it's a non-Newtonian fluid, a mixture of cornstarch and water. But I need to make sure that's accurate. Maybe check if there's any other common ingredient. The user's context mentions "What is" so I need to include that section. The user also provided a link to the full instructions at onelittleproject.com. I should mention that and maybe include a call to action to visit the site. But I can't just copy the instructions; I need to paraphrase them. Let me think about the steps: mixing cornstarch and water. The ratio is usually 2 parts cornstarch to 1 part water, but it can vary. Maybe mention that it's adjustable based on desired consistency. The title given is "How To Make Oobleck ☀️ 60 Days of Summer Activity 3 of 60 At Home Crafts and Activities for Families." So the article should be part of a series of summer activities. Maybe start with an introduction that ties it to summer and family activities. The user also mentioned "Help add more hands-on science activities to the new Touch & See Lab!" So perhaps include a section about the educational value, like how it teaches about states of matter or non-Newtonian fluids. Also, the "Learn" part could be expanded here. Jessi's in the lab mixing something strange—this could be a fun quote or example to make it engaging. Maybe use that as a hook in the introduction. I need to structure the article with natural headings. Let's outline: 1. Introduction: What is Oobleck? Maybe start with a fun anecdote about Jessi in the lab. 2. What You'll Need: List ingredients and tools. 3. Step-by-Step Instructions: How to mix it. 4. Understanding the Science: Explain the non-Newtonian properties. 5. Safety Tips: Since it's a science experiment with kids, safety is important. 6. Variations and Extensions: Maybe adding food coloring or other experiments. 7. Conclusion: Encourage sharing and visiting the link. Wait, the user wants 600-900 words. Let me check each section's potential word count. Introduction could be 100-150 words. Ingredients and steps another 150-200. Science explanation 200-250. Safety 100. Variations 100-150. Conclusion 50-100. That adds up to around 750-850, which is within the range. Need to avoid unsupported claims. So when talking about the science, stick to known facts: when you apply force, it becomes solid; when you release, it flows. That's the key property. Also, the user mentioned "Galaxy"—maybe that's part of a larger project or a theme. Not sure how to incorporate that. Maybe in the introduction or conclusion as part of the summer activity series. Check for any markdown in the response. The user wants HTML with h2, h3, p, ul, ol, li, strong, em. So I need to make sure the headings are h2 and h3, and lists are properly formatted. Avoid mentioning AI-generated. Just write naturally as a human author. Let me start drafting each section, making sure to include the required elements and stay within the word limit. Double-check the steps from the provided link if possible, but since I can't visit it, I'll rely on standard Oobleck recipes. The ratio is usually 2:1 cornstarch to water, but can vary. Maybe mention adjusting as needed. Also, safety: no eating, avoid inhaling cornstarch, maybe wear old clothes. Variations could include adding color, using different containers
