Hot WheelsColor Shifters Color Splash Science Lab Playset

Good quality plastic

My son saw this on a YouTube video so I bought it for him. He loves it. It's a great gift for a 5 year old boy at a great price. I give him a cup of warm water and a cup of cold water and he takes them out to the deck and plays with it for the longest time.

I got one for my nephew’s 3 years old birthday gift. He loves it!

we gave this as a present to our youngest son and it was great to watch his 3 years older brother enjoy playing with it as well and them sharing and not fighting! We love it

Hard to put together and kept falling apart. The cars have to be warm to change colors. The water doesn’t change the whole color of the car. Not a good buy!

The second your child expresses an interest in this toy, fake some sort of natural disaster that either a) "cuts" the power to the computer or b) requires immediate evacuation from whatever store you're currently in. I read the other reviews, but sadly, did not heed the warnings of other parents. "How bad could it be?" I thought. The answer? It's bad. It's so bad. There is water everywhere. And don't even think about trying to get anything else accomplished while your little cherub plays with this. It's taken me 20 minutes to write this review, because every 15 seconds my 3 year old is asking for more water (because the previous water is now all over the floor). "So why 4 stars" you ask? Because my son LOVES this toy. And at the end of the day, that's really all that matters. So good luck with your decision. But don't say I didn't warn you.

Good toy, watched the YouTube videos and then my 4 year old wanted this. Keep a bottle of water in the fridge for this to work properly.

The water reservoir is to small and the narrow opening begs for a car to be squeezed into it. Color change is slow to the point the reservoir runs out after one car changes color.
