# Experimental observations with sperms

**Observations done on the 5th of October 2020**

1. Cells pointing toward a side of a bubble, slowly sliding over the bubble's surface and then being sucked/trapped into a meniscus.
2. Rafts of dead cell at a distance from the bubble
3. Cells going "together" i.e. in the same direction at a short distance (synchronization? [article](https://www.researchgate.net/publication/24173210_Cooperation_of_Sperm_in_Two_Dimensions_Synchronization_Attraction_and_Aggregation_through_Hydrodynamic_Interactions))
4. "Collisions"
5. Evidence of spinning
