# Before You Spin: Securing the Clay

Your first lesson at the wheel ends in frustration if the clay flies off. Securing the clay to the wheel head (or bat) is the very first physical step, and it is not as simple as just slapping it down.

## Why Clay Flies Off

The wheel spins at high speed. If the clay is not properly attached, centrifugal force will fling it sideways during centering. A flying lump of clay is not just annoying: it can hurt, and it makes a mess.

## Slap and Stick

The traditional method for attaching clay directly to the wheel head:

1.  **Wet the wheel head** lightly with a sponge.
2.  **Smack the clay down** firmly in the center. Use a single decisive downward slap, not a gentle placement.
3.  **Press and drag**: With the wheel spinning slowly, press one hand flat on top of the clay and use the other to drag the base outward on all sides, pressing it firmly to the wheel head.
4.  **Check it**: With the wheel spinning, watch the clay. If it wobbles heavily to one side, it is off-center but also probably not attached well.

## Using a Bat

If you are using a bat, the principle is the same but you are attaching to the bat surface. Some bats have holes that grip the clay better. Make sure the bat itself is clicked firmly onto the bat pins on the wheel head first: a loose bat is just as bad as unsecured clay.

## Secure Start Checklist
Before centering:
* Confirm bat pins are fully seated
* Ensure bat has no wobble
* Press clay base outward to lock contact

This 10-second check prevents most throw-offs.

## The Bigger Picture

The outward pull that can fling clay off the wheel is described by [centrifugal force](https://en.wikipedia.org/wiki/Centrifugal_force), a concept that becomes very real when a poorly secured lump leaves the wheel head at speed. Securing clay firmly before spinning relies on [adhesion](https://en.wikipedia.org/wiki/Adhesion) between the wet clay and the wheel surface, the same molecular attraction that makes wet surfaces stick together.

## Check your understanding

### Question 1: Why do you wet the wheel head before attaching clay?

- [ ] A. So the clay stays soft
- [x] B. To help the clay grip the surface
- [ ] C. So the wheel spins faster
- [ ] D. To cool the wheel head

Tip: A slightly wet surface helps the clay grip and adhere, reducing the chance of it flying off during centering.

### Question 2: What is the first thing to check if your bat keeps moving while throwing?

- [ ] A. Add more water
- [x] B. Check the bat is clicked firmly onto the pins
- [ ] C. Use less clay
- [ ] D. Spin the wheel faster

Tip: Make sure the bat is firmly clicked onto the bat pins. A loose bat wobbles just as badly as unsecured clay.
