Tell us about yourself!
I was in a triathlon race with my son once, and there was a permanent radar speed sign on one of the streets on the cycle leg that displayed a red unhappy 'smiley' for vehicles exceeding the speed limit. We were both overjoyed we managed to get it to display the unhappy face on our bikes.. :-)
Hot glue can also be used to make soft pads that conform to irregular surfaces. I use it to make pads between bike lights and handlebars and seat tubes when the original light brackets break. Cable ties hold the lights in place, pads set the position of the light.
Acetone is naturally produced in the human body. It is only high exposure that is toxic. Acetone has been studied extensively and is generally recognized to have low acute and chronic toxicity if ingested and/or inhaledAcetone evaporates rapidly, even from water and soil. Once in the atmosphere, it has a 22-day half-life and is degraded by UV light via photolysis
..just mean acetone isn't as bad as is often thought..
