Abstract: A telephony method and system deals with telephone calls related to advertisements, such as classified advertisements. When a caller responds to an advertisement, he inputs a reference to the advertisement. The advertiser or an agent is extracted from a database, and called. The advertiser is given the option of accepting the call, refusing the call or indicating that the advertiser wishes to receive no further calls. If the advertiser accepts the call, the advertiser is connected to the caller.

Abstract: A system and method for call-back handling are described. A call from a caller to a client, is received and the number at which the caller can be called back is determined. The call-back handler then initiates a telephone call to the client through a public service telephone network standard line, either locally or on a public telephone network, and waits for the client to accept the call. Then, the caller is called and the calls from call-back handler to client and to the caller are connected.

Abstract: A jump rope which produces bubbles as it is rotated. A hollow liquid containing handle is located at each end of the jump rope. A bubble diffusor is positioned near each handle. A flexible liquid transporting tube connects each handle with its bubble diffusor. Each bubble diffusor includes coaxial tubes having an annular space between the tubes. Aligned openings are formed in the inner and outer coaxial tubes. The liquid bubble producing solution moves from the handles to the annular space between the tubes of the diffusor as the rope is rotated during jumping. The liquid bubble producing liquid spreads across the openings. Air passing through the openings in the coaxial tubes produces bubbles.
