To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
The consistency of the slime was very thin despite following instructions on the amount of water to mix it with. Consider reducing the amount and gradually adding more to cater to personal preferences. The slime was very slippery, not advisable to leave younger children alone in it. I was always nearby in case my child slipped, which he did anyway.
