I'd like you to list everything from the conventional to the unconventional. If you've tried something that you wouldn't suggest someone else to do (if you had a bad experience) please tell us so we don't make the same mistake!
For me:
- Fingers
- Pens
- Gluestick
- Opposite end of a toothbrush
- Mini baseball bat
- Ice cubs
- Frozen weiner
- Popsicle
- Metal bar from hand weights (the ones where you can remove the weights from the bar)
- Small handcream bottle
- Ping pong ball
I think that's it, but there may be more. Post yours!
