Reddit reviews Super Squirter Water Pistol 2 pack

Go online and try to find the most realistic legal toy water gun you can that can be shipped to Holland if they're manufactured outside of the country. Particularly something like this, which should be completely legal since it is a bright neon color, see-through, and does not shoot any ammunition aside from a small squirt of water.

Another thing you'll want to do is apply motion tracking markers onto the gun to make identifying and motion tracking the gun throughout any movement it or the camera makes much easier, which makes any effects and alterations on to it really fast and simple for the software. There are specially-made motion tracking marker stickers that will adhesively apply to the surface of whatever you want to track, but a cheaper (and slightly less effective, but still entirely workable if done properly) solution is to use bright (or a particularly visible color against the surface of what you're tracking) pieces of tape placed along the gun in little squares, evenly and neatly, to allow yourself to have multiple clear and visible tracking points while the gun is moving around in your hands in the shots.

Now, you'll apply several effects to the gun to A) recolor it to a dark black and remove its see-through plastic, B) apply textures and details to it to ensure it realistically looks like a gun, and C) apply a very subtle lighting effect to the final 3D object that's tracked over the water gun, to ensure that the object blends in with the rest of the shot's lighting characteristics.

I know what you mean! This is the first thing that came to mind for me too.
