Scrum does not allow making changes because, as the [Scrum Guide](http://scrumguides.org/scrum-guide.html) describes

> During the Sprint, No changes are made that would endanger the Sprint
> Goal

Although it is not described on the answer, chances are that the changes required in those experiments may endanger the Sprint Goal.

The solution will be not use Scrum but Kanban or [Scrumban](https://www.agilealliance.org/what-is-scrumban/). Scrumban which considers defining sprints as in Scrum but it allow changes as needed.
