Click to enlarge | Description:
A small bag of Sodium Thiosulfate (Dechlor) sufficient to conduct at least 30 presentations. Using three or four PIECES for each demonstration will work well in most cases. It is possible to crush 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. |
