What is the difference between putty and slime?

In a nutshell, the main differences between putty and slime lie in the structure and play experience. With putty, you experience a firm and resilient texture, while slime is soft and fluid. Putty holds its shape better, while slime can drip and pour. However, both malleable toys offer maddening fun and stimulate the senses. Which of the two best suits you or your child simply depends on personal preference.
