As state Judge Advisor, I’m making a ruling here: No dry ice. The risks
outweigh the benefits for the volunteers and the kids.

Dry ice is hazardous if handled without gloves and kids should not be the
ones handling it. Read below.
» AVOID CONTACT WITH SKIN AND EYES! Dry ice is extremely cold,
-109°F (-79°C) and can cause severe frostbite within seconds of direct
contact. (Frostbite is a freezing injury resembling a burn.)
» NEVER HANDLE DRY ICE WITH YOUR BARE HANDS. Always wear insulated
gloves. Safety glasses, long-sleeved shirt, long pants and shoes are also
recommended. Use tongs to handle blocks of dry ice.
» DO NOT PUT DRY ICE IN YOUR MOUTH OR OTHERWISE INGEST IT. If dry
ice is accidentally ingested, it can cause severe internal injury. Never put
dry ice in beverages to cool them.
» KEEP OUT OF REACH OF CHILDREN. Only adults should handle dry ice.
» OBTAIN DRY ICE IN THE FORM AND SIZE IN WHICH IT WILL BE USED.
Never saw a block of dry ice; never use a hammer to break a block of dry ice
into smaller pieces.
» TRANSPORT DRY ICE IN YOUR VEHICLE TRUNK OR TRUCK BED. Leave
windows open for fresh air circulation. Never leave dry ice in a parked
passenger vehicle. Sublimation of dry ice in a closed passenger vehicle can
result in the accumulation of dangerous concentrations of asphyxiating
carbon dioxide vapor. Dry ice can be safely transported without special
ventilation in the closed cargo area of a truck if all occupants are
restricted to the cab. When opening a closed cargo area containing dry ice,
allow the closed space to ventilate for 5 minutes before entering.
» NEVER STORE DRY ICE IN GLASS OR OTHER SEALED (AIRTIGHT)
CONTAINERS OR COOLERS. Storage in a sealed container can result in a rupture
or explosion of the container from over-pressurization.
» DO NOT USE DRY ICE IN CONFINED AREAS. Dry ice releases heavy
carbon dioxide vapor that can cause rapid suffocation.
» DO NOT PLACE DRY ICE ON A TILE OR LAMINATED COUNTER TOP. Instead,
use a solid surface - a wood cutting board or piece of plywood is best. Dry
ice is sometimes used in tile removal and may destroy the bonding agent
holding the tile or laminated material in place.
» DO NOT PLACE DRY ICE IN DIRECT CONTACT WITH PERISHABLE FOODS OR
BOTTLED/CANNED BEVERAGES. Produce may sustain severe freezer burns and
bottle/canned beverages may split or explode.

There is nothing that is banned from the presentations as long as it is not
a safety hazzard (I.e. Fireworks) but do keep in mind that the kids are the
ones that have to operate anything that is used in there presentation. If
the container is too heavy for the kids to bring in to the room it would be
ok for the parent to initially bring it in. But make sure that you bring it
up in the coaches meeting the day of the tournement to ensure that the
judges will know that is going on.

Subject: [VADCFLL-L] dry ice use in presentations
My team would like to use dry ice as part of their project presentation.
Is this allowed, and where do I find the rules on what is Ok or banned
from use in the presentations?
