I am building a trebuchet and looking for potential sources of weight for the counter-weight?

Scrap steel is around $0.15 /lb and your concrete is $0.04 per pound so steel will cost more assuming you buy it. But the cost may be worth it for the added density. Go to a slavage yard and look around. Railroad track, I beam, electric motor cores, etc may be a shape you can use. Steel chain molds to a shape or wraps around a beam.

How to take care of moths?

i found a giant moth and it's left wing was really damaged and so I put it in a container and I left the room for a few seconds came back and saw a bunch of little white egg looking things so I'm assuming it just laid eggs, I brought down an old 10 or 15 gallon fish tank.

Mustang 4.6L trick flow stage 1 cam question?

Was this rude of me to do?

i was at a friends bday party at her home. at the party she had this like blow up bouncy thing with an obstacle course inside. it was time to sing happy bday to the girl and some of my friends and i were just sitting in the little bouncy house thing. i said to my friends "we should go and join everyone" because they were doing the cake but they were like "no just stay with us". i listened to them and i know it was really mean of me. so now i heard rumors people were saying it was "bitchy" of me to not sing happy bday to her. they also said it was rude of me to get a piece of cake after not singing. i feel bad i should have went to sing happy bday.after i left the party i gave her a gift, said happy bday and thanked her. was this really terrible of me? i know it was rude, but please no mean comments

Waves/curls from cornrows?

I have AA hair (which is somewhat easy to manage because I have part indian hair) and it's completely natural, No perm, normally I cornrow it at night and uncornrow it in the morning and when I take it out it usually have nice bouncy curls/ waves which sadly Last like 1 hour or so =< so I was wondering how can I make these curls last the whole day using extra hold hairspray or something like that..... I was wondering if I sprayed it at night after I did my cornrows that they would hold through out the next day after they had been unbraided ? also does extra hold hairspray even work on AA hair? HELP please and thanks
