What is the best object to use to tickle someone with?

The most ticklish spots tend to be those that are also the most sensitive, like your: Feet. Neck. Ribcage. Many people find small, blunt, brush-like objects like back-scratchers and even hairbrushes and combs to be very ticklish, along with small rod-like objects like pencils. You'll need an object that you can lightly run across a ticklish surface like the bottom of your foot or your neck. This still won't feel like you're being tickled in as intense of a manner as when someone else tickles you, since you can't trick your brain! These objects work better on lower-body tickling, particularly on the soles of their feet. Find a hairbrush with rubbery bristles, the kind with small balls on the tips and that fan outward (scratchy bristles made of horsehair and other materials won't work as effectively).
