Have been having loads of fun swallowing this flashlight over and over again! The worst part about it is that it only lasts 9-10 minutes when shining at full brightness! Got some really good slow motion shots here while it bobs and bounces around inside me after a 2 liter water bloat!
PSA: It is NEVER safe to swallow something containing lithium ion batteries without first taking the proper precautions. I've always used a few feet of heavy duty waxed dental floss (and tightly secured knots!!!) in order to safely pull things back up after swallowing them.
