BOISE, Idaho — A local engineer does his own experiment to warn parents about light up sippy cups after hearing about a Boise mom who said one exploded in her face.
Gary Crowell said it's an experiment he wants parents to see. After warming up water on his microwave's beverage setting in a light-up sippy cup, it exploded.
"It scared me a lot," Crowell said.
Being an electrical engineer, he knew something would happen, but he didn't think it would be so significant.
"I think it was worth it to show what this can do," Crowell said.
Dzevada Becirovic said the same brand of sippy cup, Nuby, that lights up with the help of a small battery, exploded on her last week when she was pouring in milk.
Crowell said it's possible. What he's most concerned about, though, is the much more common scenario of a parent putting the cup into the microwave.
"It actually hit me when it exploded," Crowell said. "This would be terrible for a mother and child."
There's no warning on the sippy cup about keeping it out of the microwave. You can find a small warning on the paper instructions, but it's not easily seen.
"I would really like to see something done about it," Crowell said.
The company that makes the light-up cup, Luv N' Care, said all cups are thoroughly tested and inspected before hitting shelves and they're safe if properly used.
