Description:

An extra small bag of Sodium Thiosulfate (Dechlor crystals), sufficient to conduct at least 30 more presentations (one of these bags is included when the chemical cross is ordered). Using three or four PIECES for each demonstration will work well in most cases. It is possible to crush them into smaller pieces should you discover they don’t dissolve quickly enough or you desire to make them last as long as possible. Each bag weighs about four ounces.
