Endothermic Chemical Reaction || Vinegar and Baking Soda decreases the temperature

Hello friends we will learn Endothermic Reaction and it's effects on temperature
To perform these chemical reactions we are using vinegar and Baking Soda.
ambient temperature we are measuring with the help of a temperature probe and multimeter which show 25 degree centigrade and we inserted the probe inside the bottle & when we are mixing both chemical the temperature inside bottle started decreases and measured 22degree centigrade.
