So about 20 minutes ago my smoker alarms went off simultaneously for like 5 seconds, then did this again twice more within 3 minutes.Hasn't done it since but I'm worried that it could be a CO leak my alarms ARE all wired together (one goes off, they all do)
Not sure what you are asking. Are you asking how there are craters on the side facing the Earth? The moon did not always have one side facing us, that has been an development over time. And objects can certainly hit any part of the moon - the Earth is not a completely effective shield.
ive been a plumber for 26 yrs and have never heard of using epoxy putty to join pipes together, you can normally get a compression fitting for joining metal to plastic
