The two splash disks give you way more options than I expected, and swapping them out is fast enough that my kids can't lose interest mid-battle. We've had three water fights this week already.

The plunger mechanism is surprisingly smooth for something my kid assembled herself, and swapping the splash disk pieces takes seconds. It's held up through an entire afternoon of backyard warfare, which is more than I expected from a paper-based build.

We built these together on a rainy afternoon and the plunger mechanism is surprisingly smooth for something made from a kit. My son figured out the disk swap in about two minutes and now we’re having water fights in the backyard every day after school.
