ReplyDeletems zhang i changed my srp by a tad
ReplyDeleteok instead of my 3 different materials being latex, rubber and polychloroprene
i did some more research and found out that rubber balloons are made from latex and polychloroprene is really hard to find so i want to change may materials. im goin to use 2 different materials which are roil balloons and rubber latex balloons. the method is going to stay the same but the different materials are changed slightly
i meant foil not roil
