**Title:** Unofficial, but possibly "Oobleck Obstacle Course Challenge"
**Summary:**
* A group of friends, including Mike, Shawn, Lexi, and others, create a non-Newtonian fluid mixture (Oobleck) using cornstarch and water.
* They experiment with different ratios, initially struggling to achieve the right consistency.
* Once achieved, they play and challenge each other in an obstacle course setup across three swimming pools filled with Oobleck, attempting to walk, jump, and even bury each other in it.
* The session ends with a massive cleanup effort due to the pool becoming extremely cloudy from the cornstarch.
* The video concludes with the group reflecting on the fun they had, thanking viewers, and hinting at future video ideas.
Here are the key facts extracted from the text, keeping each fact as a short sentence and excluding opinions:
1. **Ratio mentioned**: 1 cup of water for every 2 cups of cornstarch.
2. **Experiment goal**: To create a mixture (Oobleck) that can be walked on.
3. **Preparation time**: The video was planned for a year.
4. **Guarding the cornstarch**: It was stored in a garage, initially guarded by a skeleton for a couple of weeks.
5. **Number of swimming pools used**: Three, for an obstacle course with different consistencies.
6. **Consistency adjustment**: The ratio of cornstarch to water was adjusted throughout the experiment to achieve the desired state.
7. **Physical properties observed**:
* The mixture could turn hard when force was applied (e.g., stepping on it).
* It could liquefy with body heat.
8. **Challenges performed**:
* Trying to get someone out of the mixture.
* An obstacle course through the pools with different mixture consistencies.
* Burying someone in the mixture.
9. **Cleanup issues**:
* The pool water became cloudy after the experiment.
* The pH and alkalinity of the pool water were affected.
10. **Video conclusion**:
* The video ended with a message thanking viewers.
* A final farewell was given ("peace out").
