fun, but the light isn't strong enough
it was fun! even for an adult kid. ha the lights weren't very strong. the instructions didn't say how long to leave the light on. 10 minutes wasn't enough when I tried it with the crank. you can put the mold with the goo in it outside in the sunlight to cure it for 30-60 minutes. with enough light, it does harden. if it is still gooey, then needs more UV light. the goo doesn't last too long, not much in the tube. only 5 colors available if you buy the extra goo on cards. it is a cool idea for a toy.
I also was able to use the ewwgoo in the Thingmaker II (2) with plastic molds. it was a toy from the 1970's
