The prince looked suitably impressed by examples of robotic machines constructed during training programs.
And sampled coffee made by some of the students.
Meanwhile, the Duchess of Cornwall, accompanied by the First Lady, visited Santo Domingo School of Arts and Crafts which provides people with the opportunity to learn traditional skills and trades such as embroidery, leather working, woodworking and silversmithing.
Magly Palacios, a teacher at the school, created a clutch for the duchess, which she presented to her during the visit.
The prince and duchess attended a Caribbean-themed sustainability fair featuring organic produce at the ambassador's residence, where all manner of traditional skills and techniques were on show, much to the prince's fascination.
The duchess was presented with a wool cape by traditional wool producers. An item which may prove useful on her return to the UK if the mild weather departs.
Afterwards, the couple attended a reception marking the 75th anniversary of the British Council in Colombia. The council promotes British education and expertise abroad and provides opportunities for cooperation in education, arts and culture. Prince Charles is Vice Royal Patron of the council.
The visit included launching the Try Rugby Colombia sports program, during which he met young people involved in British Council activities, who all looked quite happy despite the rain.
The prince posed with players involved and chatted with Foreign Minister Maria Angela Holguin.
Charles and Camilla also attended a meeting with President Santos and Mrs. Rodríguez de Santos, where they exchanged gifts.
The final engagement of the day was an official state dinner at the presidential palace, Casa de Nariño, in honour of the Prince of Wales and the Duchess of Cornwall.
The prince and duchess posed with the presidential couple for photos.
And viewed a dancing display by Colombian-born Fernando Montaño of the Royal Ballet, who performed a male version of Fokine's 'The Dying Swan' set to Saint-Saëns' 'The Swan'. The prince and the duchess are said to be fans of ballet and the duchess described watching Montaño as a "privilege".
It was a packed day for the Prince of Wales and the Duchess of Cornwall, and very much a wonderful look at a beautiful country so often, and very sadly, seen in a negative light.
