After a few minutes’ light exposure, made by the designers at baby gear company Smilo, their new glow-in-the-dark pacifiers will…well, glow in the dark. For up to three hours, in fact, which is plenty of time for post-sunset trick-or-treating hours on Halloween night. And they’re not some cheap, scary novelty either — these are BPA-free, dishwasher safe, and engineered by medical advisors, biomedical experts, scientists and industrial designers to support babies’ growing palates.
