Forms for packing sand - We are no longer selling this material but you can find it here

SoBstacker instructions (250 kb.pdf file)

Quick Instructions:

Wrap the (empty) form into a cylinder, secure top and bottom with c-clamps. Level a packed base and place cylinder on top. Shovel a layer of dry or moist sand into form (6-8 inches deep.) Pour in water and mix well. Allow to let settle - tap the sides or tamp with feet or other implement. Repeat until form is filled to desired height. Remove clamps and carefully peel form. Carve as desired.

Quick Tips:

1. We recommend a 18" overlap (minimum) and our standard form sizes reflect what size cylinder you can expect if you follow this advice. However, there is wiggle room here. Going smaller is no problema whatsoever as multiple times around will only strengthen the form -- but you may also be able to go a bit larger as long as you keep some overlap and don't pound too hard.

2. If you are experiencing many collapses upon peeling of the form, try a.) using more water; b.) tamping harder; or c.) filling up the form only halfway. RESULTS WILL VARY ACCORDING TO QUALITY OF SAND.

About the Set

If you max out all three forms you will end up with a configuration similar to the one in the photo below - just under 5' tall. If you place your bottom form on a raised (wetted and packed) base and do some handstacking on top you can easily attain 6' or taller in height with these forms. Roll them up inside each other and they fit into an 18" or longer duffle bag for easy transport.
