How can make a >4% agarose gel?

I always use 4% NuSieve low melting temperature agarose to separate my small DNA
template (~100bp).  For even smaller DNA template, such as less than 80bp, I
would recommend to use nondenaturing polyacrylamide. Metaphor agarose is more
expensive and hard to make 4% gel.
